Demo of having OpenAI's Codex explain how a Python function works in plaintext

Can't wait to just let codex create comments to explain to people what my code does! :')

sick. but you should've given more complex code to see if it works

This will really improve programming in the future If it really works as well as this video shows

Do you think it's too late to start learning programming, software developing etc absolutely FROM SCRATCH now taking into account all the advances in technology? Or here's another example. I think you are in your early 20s now ( please, forgive me if I'm not right) . So, if you were now in your 40s-50s and had to start completely from scratch, would you still choose the same path ?
I really need some advice cause I don't know if it's a good decision
