that's not really a justification in my view. The entire education industry is complicit in this circus. It's not just engineers hoping to get a payday it's academics too that are hoping to get funding and tenure.
CACM was totally complicit in spreading the blockchain hype: https://cacm.acm.org/?s=blockchain
That said, I'm not hating the player, people gotta eat. But I totally lack appreciation for the game.
I've worked in the analytics space for over ten years building what today is called "AI" as a service or product. The hype seems more like pent up release for the valid stuff, and block chain for the tech marketer type stuff.
