AI isn't a magic human replacement in most fields at the moment.
What language models allow is automate tasks that couldn't be automated before. For example, if you spread a 10% time gain from the people who are already working, you are going to hire 10% fewer people.
I'll say here, where no one knows me, that GenAI tools have probably cut my workload by half. Probably more if you discount the amount of time I spend staying ahead of folks. I can also say that none of my teams have had additional any headcount approved in the last 2 years.
That honestly sucks as a zoomer. I will say that the people we have added to teams have all came from internal promotions or acquiring small companies. Maybe start a passion project company and start building something even if it doesn't make money and is mostly on paper.
