I just remembered the NFT hype was only three years ago, and has already fallen into complete obscurity.
This in turn made me remember a Razem National Council session back 2019 (I think), where we were discussing self-driving cars as a potential future challenge to employees (particularly lorry drivers). That one's fallen into obscurity. too. No one's waiting for self-driving cars anymore.
The "AI" hype is in its second year now...
