> A back-of-the-envelope calculation finds that covering aicapex through identifiable ai income requires revenue on the order of $2.5trn per year, more than tech’s entire combined revenue today.

…

> All these complex calculations roughly tally with a much simpler one: adding up the ai revenue of the firms selling most of the ai. Anthropic pulls in perhaps $75bn, annualised; Openai makes tens of billions; Google, via its ai model Gemini, and Microsoft probably get a bit less. SpaceX may have a few billion dollars’ worth of revenue from enterprise aithis year. Meta also makes a few bucks from ai. Add this up and you land at roughly $150bn a year.

$2.5tn is about 8% of U.S. GDP. So a handful of AI firms really expect that they will become larger than the entire U.S. sectors of manufacturing, government, or healthcare?

Investors expect that they will, I guess. If you really believe the strong ai use cases (like exponential improvements, or it replacing hundreds of knowledge workers at every company" then maybe this isn't unreasonable.

If many people lose their jobs, thus consumers having less and less money, where would that money come from?

Depends how many people, but don't forget that:

1) people like me exist: I don't live in the USA, yet it is possible for me to buy things which are made in the USA

2) fiat money is only created or deleted by laws the government controls (plus a tiny quantity from forgery and damage to coins and notes), so everyone losing their jobs doesn't make the money disappear, just who has it available to spend

3) previous waves of automation have created new business opportunities; while this has not been too good for the people who lost jobs to the automation, it has generally boosted the overall economies this happened in, so it is absolutely possible to wipe out tech employees without it seriously harming consumers collectively

If you look at recent trends in consumer spending, a lot more of it is from the upper classes and less from the middle. Selling services to the rich can displace the loss of white collar workers. (in theory). as a bonus, ideally you create some more really wealthy people to spend on things during this shift.

		I'm yet to see what part of AI really wealthy people would like to spend their money on. It's not like we can get AI Yachts and AI Rockets. What would the premium product for the upper class be?

I guess the bet is that they will become embedded in basically 8% of the tasks in every sector. which I guess could happen long term? thinking about the whole ass economy in this way always make my mind boggle so I don't really feel equipped to talk intelligently about this.

I suspect that they believe they can integrate with a substantial portion of not just the US economy, but also most of the European and formal Latin America economies. And I also suspect that the number is quite high because there are so many AI companies planning to snag like 80% market share for AI.

The share price is based on them eliminating entire sectors yes.

I thought SpaceXAI was making like $25 billion a year renting out hardware now?

Why would capex need to be covered by income during a time of investment and infrastructure buildup? Did income from the Apollo program cover its expenses?

Public investment was responsible for Apollo, so there was no expectation of profitability. Private investment is largely responsible for the AI buildout, and private investment isn't doing that for charity

If I give you 5 trillion dollars I want to get that back plus a percentage increase on top for my troubles, right? Government programs might run without the expectation of paying back taxpayers but investors are less generous.

Investors can be very generous if they see opportunities for market capture of the next big thing

		Also they might not be as smart as they have made out to be. This time it seems they might be spending more to capture market than the market is worth. Still, there are plenty of people who take their cut of the money on the way. So at least those people will be happy.

Because most of the capital assets depreciate over a period of 5 years or so so you have to make the expenditures back during that time or you can't book any revenue.

The Apollo program wasn’t for profit and if it was it never would have yielded a return on investment.
