I had a look at the numbers.
The investment into data centers is estimated around $800B/year currently.
OpenAI + Anthropic combined had ARR of >$100B in July.
Global labor income is around $65T/year, the US GDP $32T, the global one $126T.
Global software spending: $1.4T/year.
I am no financial analyst, but I don't think all the stated AI impacts have to be met just to recover the investments.
A 1% productivity gain on global labor income represents $660B/year. At 5% we would look at $3.3T/year.
They don't need to cure cancer to justify the investment, even though Amodei hopes to cure most major disease in the next 5-10 years.
