What makes this time weird though is back then (and in most bubbles) the bubble was creating jobs - supposedly (I'm too young) anyone who could write a bit of HTML could get hired in the dot com boom.

Whereas this is a very weird bubble where it creates big pumps in some equity prices but apart from a tiny number of people who are directly involved in AI research etc. it's not created any jobs, in fact by creating uncertainty it's probably caused fewer jobs to be created.

What that means for labour market dynamics when it pops I really don't know

It's no coincidence that daytrading ascended with the dotcom era.
