Yes, if you find something else better it might well be the smartest thing to do. Forewarning "the naive and dreamers" is little different from offering sound advice to those who are neither. As for the OP's post, you might want to research their history and revisit that comment.
Flying is a game for idiots and losers with no other options
No it isn't. For some it is a well planned and researched career with good rewards. I say that because I fly (and have done for nearly two decades) with so many of them. Not one of them is either an idiot or a loser. In fact quite the opposite.
Only those who are already too old to adapt have any excuse for staying.
That rather assumes that they need an excuse? If I align myself to that demographic I still adapt all of the time. The time to retire is when that becomes too difficult, or when you reach the regulatory number.
