Ask HN: Advice for a person in their late-20s switching careers into tech

Hi all, its 2023 and AI is going to take over a lot of jobs. So what advice would you give, to someone who is in their late 20s, for switching from a non-tech related career to tech?

Alternatively if you are a person in this field and would have to do things again from start then what/how would you do things differently given that its 2023?
