This stuff is basically just resume bling... like an unpaid internship at a prestigious law firm... or a college diploma.
Jumping on dumb "cutting edge" trends like this is a way for the people involved to establish themselves as "movers and shakers" in the tech world, which will make them a hot commodity for a) clueless corporate hiring managers who don't actually know anything about the business, b) tech illiterate con-artists "tech" entrepreneurs looking to make a lot of money by inventing the next dumb cutting-edge trend, and c) other would-be "movers and shakers" in need of some extra legitimacy for their own cutting-edge project (usually meant to pull the same trick).
None of these project need to make any money, or even deliver a product to pay off for the people behind them. Ultimately they will collect at some point down the road thanks to the the generosity of lazy/elitist corporations and fraud victims. It's an entire global industry of wearing and selling the emperor's new clothes, continuously playing out on multiple layers. And it is one of the pillars of our entire modern technological civilization...
