Hi! I am the author of that article.

> I don't get how people can spend roughly 3 months learning to code and make a career out of it. Surely they must be lacking in certain core areas of CS.

I kinda agree with you. One usually does NOT make a career in 3 months. But who says you can't? I definitely will fail all coding interviews even now after 1.5 years of practice. But I built a real SaaS app that people are paying for. It's not the best architecture. I am sure it will fail at scale. But hi, fuck it, I built something of real value.

The title is a bit clickbaity - but still true. Anyone can learn coding, no matter the age.
