Though the FTSE All-World index (or the S&P 500) is also at all time highs, so I would expect most stocks to be at all time highs, too.

I guess you can try to outbid other people? But thanks: I didn't know the data-centre-building industry was so supply constrained at the moment.

I knew you'd say that. SMCI though. It isn't just the macro. It is this AI stuff and has been going on quietly behind the scenes for the last 1.5-2 years now. Unless you're deep in the business, it just doesn't make the news headlines because it is all so intrinsically hush hush.

The whole supply chain is borked. Try to buy 800G mellanox networking gear. 52 week lead time. I've got a fairly special $250 cable I need that I can't get until April. I could go on and on...

Thanks a lot!

I've seen some of that playing out in a business that was using GPUs for deep learning as applied to financial market making. They were throwing a lot of money at nvidia, too.

I wonder if it's enough money in total in AI to show up in countrywide GDP figures anytime soon. Because either AI's hunger for ever more computing power has to slow down, or world GDP has to increase markedly.

I am pretty convinced that it won't ever slow down. The need for compute is infinite. I'm super biased on that opinion though, obviously.

Well, I'm talking about the rate of increasing slowing.

Given the speed of light as an upper limit, in the very long run we can at most have a cubic growth, not an exponential growth. Something will have to give eventually.

(OK, you also probably need to Bekenstein bound. Otherwise, you could try sticking more and more into information into the same amount of space. But there's a limit to that, before things turn into black holes.)
