One of them is "I spent years to learn this and now these plebs can just learn it in 3 months then take my title?". I'm not saying this is _your_ emotion, but I certainly notice this in me.
Anyway, I think this kind of emotion is not productive. If programming really is so easy to learn then maybe we made a big mistake by taking a 4 year university program to learn it.
That said, I actually think programming is hard and whatever you learn in a 3 month bootcamp will in no way give you all the tools and experience you need.
The problem though is the average.
New programmers look out to what everyone else is doing in order to learn.
But because most programmers are beginners, it ends up just being a cycle of beginners teaching each other.
When people with experience do speak out, what they say sounds so completely different from what the rest are saying, so the beginners don't listen to their advice. They will think these people with contrarian perspectives are just weird.
