Why every time a beginner is shouted “You will not succeed, because it is very difficult”?

Question

Career in IT

Good evening!
I constantly read a toaster, from my very busy schedule I find 15 minutes a day to read.
It's always a pleasure for me to read good answers to newbie questions, because I'm one of them myself. But for some reason, every time I read lines like these "You won't succeed, because it's very difficult," I'm perplexed.
For me it's like a challenge, I'm already used to these words, they constantly told me, they say, and they probably will say them ... but it can break someone at the very beginning of the path. To a completely "green" newcomer, this is like a STOP signal. And I also noticed, they say already eminent, in my opinion, toasters. They say those who have gone through all this, studied and know (question, problem, topic ..). Why?

Answer 1

Yes, no one here says that, throw a link, give proofs to us))

Answer 2

In general, if you have seen such phrases somewhere, then this may be something like a dropout, remember the first part of the film Full Metal Jacket?)

Answer 3

Because they are afraid of competition.

Answer 4

Because they didn't make it. This is their experience, so they share.
Sometimes they're right, sometimes they're wrong, either way, it's up to you to try and decide.
