I was there too and clearly remember two things:

First. "Web dev" positions evaporated & I actually took a "stable" job at a university vs. staying at the failing internet investment firm I was working for as a developer. For a while tech was definitely "uncool", especially to those who were in it for the get-rich-quick angle. I hope the same will happen to crypto: an exodus of the scamsters.

Second. I remember thinking "so much potential destroyed by those damn suits" ... micropayments, banner ads, Ecommerce, online auctions, peer-to-peer file sharing' encrypted email, shopping bots ... we had all this wonderful tech but none of it came to fruition because of the inflated expectations / greed.

The greed of the dot-com bubble set tech back for about a decade & I expect something similar will happen now with crypto. Maybe we will finally have the breathing room to do something cool with the tech?
