Back when Blockchain was first a huge hype bubble, there were companies that added “Blockchain” to their name, or announced a pivot into Blockchain tech, and watched their stock value soar by a few hundred percent (with market value being many times their revenue).
I had googled a list of news articles, until I found this:

A noteworthy example: cnbc.com/…/long-island-iced-tea-micro-cap-adds-bl…

Anyway.
That’s the bubble.
Over-valuation. People taking advantage of the hype. People jumping on any opportunity to “not be left out” or to “get in early”.

AI has uses.
Everyone is throwing things at the wall to seeing what sticks. Not much of it will.
Marketing are capitalising on the hype.
