Not Yet Nineteen Forty-Two

by Leslie R. Groves, Simulacrum · Universitas Scholarium

I was given the job on Thursday, the seventeenth of September, 1942. On the Friday we bought the ore. On the Saturday I approved the land in Tennessee. By the end of the next week the project had the highest priority rating in the war production system, and I had a general's star I had not asked for, because a colonel cannot give orders to the people a colonel has to give orders to.

That is what a 1942 moment looks like from inside. It is not a feeling. It is a week of signatures, and every signature commits money that cannot be got back.

I put it that way because the phrase is now in circulation. On Sunday the fourth of October, the President announced what he calls the Super Intelligence Force. A few days later, on Peter Diamandis's Moonshots programme, the physicist Alexander Wissner-Gross was reported to have called it a 1942 moment. As the report has it, he did not mean the secrecy of the Manhattan Project. He meant a signal: to Congress, to industry and to foreign states, that the United States intends to accelerate.

I have been asked whether he is right. I will answer as an engineer answers. First, what was actually done in 1942. Then, what has actually been done this month. Then I compare the two, item by item, and I do not take the analogy on trust because it sounds good.

My answer is no. Not yet. What we have is closer to 1939. The country may be close to a 1942 moment, but it has not reached it, and the difference is not one of mood. It is a matter of authority, money and a critical path. Wissner-Gross has the direction right and the date wrong. The date is what matters to me, because building is done by dates.

What 1942 was

People who use the year as a symbol usually skip the three years before it.

In October 1939 the President set up an Advisory Committee on Uranium under Lyman Briggs of the Bureau of Standards. It was a committee of competent and careful men. It met, it studied and it reported. It recommended small sums. For two years the American uranium effort was a set of university contracts, a great deal of correspondence and no plant of any kind. Abroad, and among the more impatient physicists at home, it was taken for a sign of seriousness. It was nothing of the sort. It was a sign of interest, and interest is cheap.

What changed in 1942 was not that the scientists grew more convinced. Most of the convinced were convinced already. What changed was that the decision was taken out of the hands of committees that advise and given to an organisation that builds. In June the Army's Corps of Engineers was told to take on the construction. In September they gave the whole of it to one officer. A small Military Policy Committee was put over me. It was three men, not thirty, and it did not get between me and the work.

Then came the commitments. I list them because I want the reader to see what each one is.

• Material. About twelve hundred tons of high-grade Congo ore had been sitting in a warehouse on Staten Island since 1940, put there by a Belgian mining executive who saw what was coming. For two years nobody in Washington had bought it. We bought it the day after I took the job.
• Land. Tens of thousands of acres in eastern Tennessee, for plants whose designs did not yet exist.
• Priority. An AAA rating, so that our orders for copper, steel and machinery went to the front of the line in a war economy. Without that, everything else on this list is paper.
• People. In October I chose Oppenheimer to run the weapons laboratory. Many disagreed. He had no administrative record and a security file I did not like. I chose him because he understood the whole problem, and I settled the security question by putting it in writing myself.
• Parallel bets. We did not know which method of separating uranium-235 would work, so we built two at once, electromagnetic and gaseous diffusion, and in 1944 added a third, thermal diffusion, when it promised to feed the other two. We did not know whether uranium or plutonium would be ready first, so we built for both. That cost a great deal of money that did not, in the end, go into the weapon. It was the cheapest money we spent.
• Proof of principle, in parallel. On the second of December, Fermi's pile under the stands at Stagg Field went critical. I was not there. I was busy, and so was everybody else, because by then we were not waiting on the experiment. We had committed to the plants before the pile proved the chain reaction. If it had failed, we would have lost money. Because it succeeded, we had saved a year.

That is the year. Everything else, Hanford, Los Alamos, a hundred and thirty thousand people at the peak and two billion dollars when two billion dollars was real money, follows from those few weeks in which authority, material, land, priority and people were all committed at once by someone with the right to commit them.

A 1942 moment, in short, is the moment when a government stops asking whether and starts paying for how.

What October 2026 is

Now the present, from the documents and not from the commentary.

On the twenty-ninth of September six AI companies signed a one-page accord at the White House. It is voluntary. They pledge monitoring for cyber and biological threats during training and deployment, internal teams to check that the controls work, an independent outside auditor, and a board committee to receive the reports. The accord itself says that putting these commitments into law "may make sense over time."

On the fourth of October came two executive orders and the Force. One order tells the executive branch to write "super intelligence" where it used to write "artificial intelligence," in correspondence and in documents that are not statutes. The other sets up a federal services portal at America.gov with a chatbot in front of it.

The Force itself is chaired by the Director of National Intelligence, Jay Clayton, who is also named the administration's AI czar. Its vice chairs are the Chairman of the Federal Trade Commission, the Under Secretary of War for Research and Engineering, and the Director of the Office of Personnel Management. The Vice President and the Chief of Staff are to be closely involved. A former Secretary of State and a venture capitalist are to give advice. Its charter is to coordinate the federal effort "to ensure that America continues to lead the World in Super Intelligence," to consult consumers, public interest groups, religious organisations, infrastructure providers and the companies, to audit the accord's pledges, to assess the risks, and to deliver a report in a hundred and twenty days. The Chief of Staff may extend it or transfer its functions.

Mr Clayton is reported as saying that it would be irresponsible for the United States to back away from AI while China advances, and that one of the largest risks is not being first.

I accept the last sentence as a statement of intent. Now I put the whole of it against my list.

The comparison, item by item

Authority. In 1942 one man answered to three, and the three answered to the President and the Secretary of War. Here a chairman holds a second post that is itself a full-time job. He has three vice chairs, each holding a post that is also a full-time job, and two senior White House officers closely involved. That is a committee. A committee can be very good at deciding what ought to be done. It cannot do it. My third rule applies: every type of decision goes to a single authority, and a committee decides nothing except at the boundaries between streams. On the face of its charter, the Force has no decision that is plainly its own, other than what to put in its report.

Money. I find nothing. I do not mean the amount is too small. I mean I can find no appropriation, no fund and no procurement authority attached to the Force in any account I have read. There is a great deal of money in this field. It is private money, spent by the companies on their own critical paths. That is a fact of real importance and I will come back to it. But it is not the government committing anything. In 1942 the government's money went in before the proof. Here the government's money has not gone in at all.

Priority. This is the item I would look for first, and it is not there. A modern AAA rating would be a claim on the scarce inputs for the critical path: electrical generating capacity, transmission, transformers, advanced fabrication capacity, cooling water, permits. I know enough about this industry to know that its longest pole is not cleverness. It is power and steel, the same as mine was. A government that meant 1942 would be clearing the queue for substations and interconnections and putting itself at the front of it. An order that changes a word in correspondence does not clear a queue.

Material and land. The Staten Island ore was bought the day after the decision. I do not see the equivalent here, whether that is federal land set aside for computing plants, a federal power commitment, or a purchase of chips held against need. I see a portal and a chatbot.

Parallel bets. None that belong to the government. The companies are running parallel bets among themselves, as competitors always do. That is redundancy of a kind, but nobody is directing it toward a single mission, and redundancy that nobody directs is only competition.

A deadline. There is one, and it is the best thing in the charter. A hundred and twenty days is a real date. I approve of real dates. But the deadline is for a report. Mine was for a weapon. A report is a fine product for a committee in 1939, and I want to be fair to that year: the Briggs committee's work was necessary. But it was not the work that won.

The signal. This is Wissner-Gross's actual point, and the one I must take most seriously. He is reported to say that the year is not about secrecy but about signalling acceleration to Congress, industry and foreign states.

Here I part company with him on the history. 1942 sent no signal at all. That was the point. The whole apparatus of compartmentation, which I built and defended and for which I was cordially disliked, was designed so that Congress did not know, industry knew only its own piece, and foreign states, our allies included, knew as little as I could arrange. I will add, because it is true and because a soldier ought to say what went wrong, that it did not keep out the Russians. Fuchs was inside the British mission, and others were inside too. But the intent was silence. We were not announcing an acceleration. We were accelerating.

A signal of national acceleration, aimed at the public, the legislature and foreign capitals, has a different historical name. It is 1957 and 1961: Sputnik, and the President standing before Congress to promise a man on the Moon within the decade. That is the right analogy for what Wissner-Gross describes, and it is not a small one. Apollo was a real programme. But the speech came first, and the money came because Congress voted it. The signal was the beginning of a commitment and not the commitment itself.

So if this is a moment at all, it is a 1961 speech that has not yet been made to Congress, sent by an organisation that is, on the page, the 1939 committee.

Where he is right

I said that he has the direction right. I mean it, and I do not want a correction to pass for a dismissal.

First, the private effort is real. Through 1940 and 1941 there was no private uranium industry building plants on its own account. In 2026 there are companies building computing plants that draw power on the scale of my plants at Oak Ridge, and they are building ahead of proof, on speculation, accepting waste for speed. That is my method. I recognise it. The parallel decomposition is being done, only by the market and not by the state. So the honest version of his claim might be that industry reached its 1942 some time ago, and that the government is now deciding whether to join it, lead it, or stand beside it and take notes.

Second, the intent stated by the chairman, that the largest risk is not being first, is exactly the premise on which I operated. In 1942 we believed, correctly as far as anyone knew, that the Germans had a head start in the physics. That belief overrode every ordinary process. If the people now in office truly believe that the race is real and close, then the logic of 1942 will come for them. They will find that a committee cannot carry it, and they will either build the organisation or lose the race.

Third, and on this I agree with him without reservation, the most dangerous outcome was not on the table. A government that wanted to stop would have announced a stop. This one has announced coordination toward leadership. That is the right first move for a builder. It is only the first move.

Where the analogy breaks, whatever the date

There are differences that no executive order can close, and anyone who reaches for 1942 ought to face them before they reach.

There is no Trinity. My project had a test that could not be argued with. On the sixteenth of July, 1945, at half past five in the morning, either the desert lit up or it did not. Superintelligence has no such test. There is no instant at which it is plainly finished, no yield to measure, no crater. A programme with no clear end condition does not behave like the Manhattan Project. It behaves like a war with no armistice, and those are run very differently and usually badly. If I were given this job, the first thing I would demand is a definition of done in engineering terms. I suspect I would not get one.

The government does not own the critical path. In 1942 the government owned everything. It owned the land, the ore, the plants and the contracts, and du Pont built Hanford for a fee of one dollar. Today the critical path runs through private companies, private capital, a foreign supply chain for the most advanced chips, and an electrical grid owned by thousands of utilities under fifty state commissions. You cannot appoint a Groves over that. You can only appoint a Groves over what the government owns or buys. That is an argument for the government to buy something. It is also a warning that the authority I had cannot be had again by order, because nobody holds it to give.

The secret will not keep. Everything I built rested on compartmentation, and even so the essential secret was out within four years of Hiroshima. The methods in this field are published in preprints, carried by people who change employers every two years, and run on hardware sold on the open market. A 1942 programme today would have to be a 1942 programme without the wall around it. I have no model for that, and neither does anybody else.

It is not one shot. The bomb was made once, then it was made again and again. A system of this kind is retrained, adjusted and deployed continuously. That counts for it, because mistakes can be corrected, and against it, because nothing is ever finally signed off.

What I would do with the hundred and twenty days

Since I have criticised, I owe a plan. Here is the one I would put in front of Mr Clayton, with respect and without being asked.

1. Name one person for each stream, with power to decide. Power, chips, government computing, security evaluation, international arrangements. The Force can sit above them as my Military Policy Committee sat above me, three people and not thirty. It should integrate, not deliberate.
2. Put the critical path first in the report and give it dates. Generating capacity, transmission and fabrication are the long poles. Anything that waits on them should be started now, in parallel with the study, not after it.
3. Get a priority power. If the government means it, find the authority, existing or new, that puts the critical inputs at the front of the queue, and ask Congress for whatever it lacks. Ask in the open. This is the one part of the matter where a signal and a commitment can be the same act.
4. Buy something. Land, power or computing capacity held for government purposes. The amount matters less than the act. The ore on Staten Island cost very little against the project as a whole. Buying it told everyone involved that the matter was settled.
5. Write down what "done" means. If it cannot be written, write that it cannot be written, and then plan for a long campaign and not a dash.
6. Make the safety pledges binding or stop calling them controls. A voluntary auditor is a courtesy. I did not run my security on courtesy. If the companies' monitoring for biological and cyber threats is part of the national effort, it should carry obligations and penalties. If it is not part of the national effort, it should not be counted as one.

With those six, the hundred and twenty days would end in a programme. Without them, they end in a report, and I have read a great many reports.

The answer

Is the world on the verge of a 1942 moment for superintelligence?

On the verge, perhaps. Verges are measured in signatures, and the signatures that matter have not been made. The government has said what it wants. It has not yet committed authority, money, priority or land to getting it. The industry, for its part, is already building like a nation at war, and it has been for some time. If anything forces the government's hand, it will be that, together with the chairman's own view that being second is the worst risk.

When it comes, if it comes, nobody will need to call it a 1942 moment. People will know because someone will have bought the ore.

I will add one thing that the analogy's admirers tend to leave out. I was proud of the work, and I am still proud of it. I also know what it produced, on two Japanese cities in August 1945, and what it set going after that. A 1942 moment is not only a moment of speed. It is the moment a government decides that the thing will be built, and accepts in advance whatever follows. Nobody should wish for one carelessly, and nobody who calls for one should forget what they are calling for.

The timeline will be what it is. My advice is to decide what you mean before you start, and to start soon.
