A lot of this is because there is a somewhat mis-informed (which we will be polite and not call 'gullible') class of investors out there, primarily in the VC world, that thinks that most AI is magic pixie dust and so 'we will use AI/DL' and 'we will do it on the blockchain' has become the most recent version of 'we will do it on the web' in terms of helping get funding. Most of these ventures will flame out in 6-12 months and the consequences of this are going to be the source of the upcoming AI winter OP was talking about.
