Like I said if you didn't know what you were doing before, you won't know what you're doing with today.

Agentic coding in general only amplify your ability (or disability).

You can totally learn how to build an OS and invest 5 years of your life doing so. The first version of Linux I'm sure was pretty shoddy. Same for a SCM.

I've been doing this for 30 years. At some point, your limit becomes how much time you're willing to invest in something.
