"Some programmers are awesome at 18. Others are awesome at 40. You can’t base your decisions about programmer quality on age"

It's a quote from the same post. Of course you learn better when you're young, and that's not only programming, it's everything.

Notice here "great programmers"  is a really great thing. You can still be a good programmer even if you don't meet those patterns. And remember they are not always right. There are exceptions too!
