Larrabee to my understanding didn't have AI in its mind, it was all about proper ray-tracing for gaming and therefore something that had very little realistic chance of delivering a usable result for a very long time. In games ony "faking" would perform well enough for many years and Larrabee would have only had a niche in rendering farms.
Intel has quite often gone in the right direction but completely failed in the execution of the path: this was another of those moments where PG looked in the right general direction, but failed to properly map and execute the path.
The follow-up architectures were also all about HPC, no AI extension support at all as far as I recall and there Intel tried to play the exclusive x86 card while everybody was still hurting from arms twisted by Itanium. And their insistence on Hybrid Memory Cubes (HMC) instead of High Bandwidth Memory (HBM) didn't help, either. My former colleagues at Bull spend enormous budgets developing products for both architectures and might have fared better if they had not.
In my view Intel played poker and lost, deservedly.
Nvidia saw an opportunity and quite simply used it... very well and without ever letting up.
The opportunity was luck, what they made of it is the reason Nvidia is where they are today.
Contenders were obviously either not trying hard enough (IBM), were still riding the wrong horse (Intel) or didn't have the funds to keep up (AMD).
And Gelsinger talking about Intel aiming at "democratizing AI" reminds me of
PiS rethoric, where after years of trying to Orbanize the media, kicking PiS ideologues out of tax payer funded public media is criticized as "anti-democratic".
Alternate facts are becoming a very popular in the US and I just hope that some people will retain their brain and take PG at face value, even with all AI generated content trying to pull them into buying from the sponsor.
