Perhaps it's something up with which he will not put. (Stolen from someone famous whose name I can't remember.)

I've never attended ISC, and it is unlikely I will ever attend unless I get rich enough to afford it on my own dime.

With ‘AI slop’ distorting our reality, the world is sleepwalking into disaster | Nesrine Malik
A perverse information ecosystem is being mined by big tech for profit, fooling the unwary and sending algorithms crazy, says Guardian columnist Nesrine Malik

The thing is, gallium arsenide will never come even close to being as cheap as silicon.
Don't get me wrong. I like GaAs. I got my Ph.D. by bouncing low-energy electrons off of the (110) surface of pure GaAs single crystals. 😜

GaAs has been the semiconductor of the future for decades, presumably because of its higher electron mobility. Unfortunately, Seymour Cray's CRAY-3, based on GaAs, was no faster than the ho-hum silicon CRAY C90 when they both became almost simultaneously available in the mid 90s.

The directive-based predecessors to #OpenMP that were available in both Cray Research, Inc., and Silicon Graphics, Inc., compilers in the early to mid-90s. After the so-called merger, OpenMP arose from both.
