something like that, but smaller

look at the taxi industry for example for decades no events, then uber came in, then grab, then uber exited. (this happened in less than 10 years)

if one was a guy who is in the taxi industry, the entry of uber to the exit of uber, both are career changing and potentially career ending.

then, those who picked it up first, earned a huge boon waaaay more than any taxi driver could, but then those who joined late, get into hardship

i started noticing this in university programmes also

like its quite unheard of for a market to totally not need engineers in a short span of 2-3  years, before 00, yes it happens when a market crash like 98 happened. But if you went in in 89, chances are you'd get a job in 91'.

now, you go into uni in the next 3 years your job may not even exist
