Science is not merely computing though, even the theoretical sciences

Just to re-iterate the point:

Whenever the handwaving starts around a discussion relating to a NP hard problem, I find it useful to imagine a Canadian bloke (MHRIP) in a red top, with a ... Scottish accent ... saying:

"Ye cannae break the laws o' physics, Jim". (maffs not fisics, obvs!)

If that is a bit tiresome for the gung-ho AI evangelist, there is also the rather knotty snag that that blasted Austrian geezer Gödel fiddled up: incompleteness.

Its almost as though these bloody clever scientific and that types keep on putting artificial blocks in the way of LLMs laying golden eggs!

I'm quite happy with the "marginal gains" I get with a DGX Spark. It will pay for itself within three months doing stuff on prem and us not sending data to someone else. It will scale.
