Sure there is a lot of hype in AI/ML right now, but this post reads like there is an axe to grind with all ML. it ignores true progress made in a lot of areas and denigrates the whole field. to me it did not read like an objective post, but more like just a "all AI is bullshit" style blog post
Anytime there's new progress in AI, you will see many comments or posts some variations of "but humans do it more efficiently" (in arbitrary dimension) or "what about the other problem AI didn't solve". More often than not these are just some lazy layman criticism that makes the posters feel smart without offering anything new or substantial.
