Hey! So you may have noticed that you got downvoted into oblivion here. It is because of the unnecessary amount of negativity in your comment.
In communication, there are two parts - how it is delivered, and how it is received. In this interaction, you clearly stated your point: giving yourself the title of pro oftentimes means the person is not a pro.
What they received, however, is far different. They received: ugh this sweaty asshole is gatekeeping coding.
If your goal was to convince this person not to call themselves a pro going forward, this may have been a failed communication event.
I know someone who got it at 17. That said, the only reason it happened was because of connections. Usually, even if it gets approved at 16, you basically have to get in line, and that will take 2-3 years before you can actually get the surgery.
That’s how it was for my friend a few years ago at least.
