Hm. I agree about the hype trend, but Intel is a for-profit company. You're saying Intel saw an opportunity to make a quick buck on the stupidity of a bunch of other company executives, and decided to hard-pass on a quick buck?
While it's reasonable to speculate that there are bubble-like qualities to the "AI" industry (primarily due to failures to provide return on investment), from Intel's perspective, this shouldn't matter.
The enterprise GPU makers are the shovel manufacturers in the gold rush so to speak.
But Nvidia already had chips and cards shipping that were suitable for AI, so not tons of R&D up front. Intel would have to somehow make their ARC line better for AI and do it faster than Nvidia is improving theirs.
