> Compute costs fall reliably, so what matters is the capability at a given price point in 18 months, not today.

The underlying point still stands, namely that "more compute" as the default answer is not sustainable.

Why ?

Because even if we accept the unlikely dream that GPU prices will magically take a nose-dive, you still need somewhere to put all those servers stuffed with GPUs.

That means datacentres.

And "more datacentres" is absolutely not sustainable.

The cooling needs, the power needs, the land needs..... none of it is remotely sustainable.
