AI capex is so big that it's affecting economic statistics

I don't know... 1.2% of GDP just doesn't seem that extreme to me. Certainly nowhere near "eating the economy" level compared to other transformative technologies or programs like:

- Apollo program: 4%

- Railroads: 6% (mentioned by the author)

- Covid stimulus: 27%

- WW2 defense: 40%

Yeah that's my first reaction to. 1.2% doesn't sound much. It's just people making headlines out of thin air. If it lists the water and energy consumption I might be more concerned.

Slightly off-topic, but ~9% of GDP is generated by "financial services" in the US. Personally I think it's a more alarming data point.

Why is 9% for financial services bad? This should cover fees/interest from everything like loans, transactions, mortgages, advice, investing, etc. It doesn't seem that surprising to me that the systems that are the backbone for all the money operations that power the rest of the economy make up about 10%.

I get your point, but the flip side is that private companies like visa and Mastercard get to skip 2.5%+ off the entire economy. Visa has more than 50% profit margin, and it’s not like these companies are innovating with all that extra cash either. It’s just money from my pocket to some rich investor somewhere

Visa and Mastercard aren’t skimming 2.5% off the economy; the majority of the interchange fees go to banks (which Visa is not; their actual product is VisaNet which provides payment infrastructure, broadly.)

Trivially verifiable by Visa’s revenue being $35B, which is not even close to 1% of just US GDP (about $30T).
