You haven't mentioned anything specific about dangerousness of goto. The fact that you heard some conclusion is irrelevant, unless you pass the reasoning behind it. If goto is dangerous, why isn't if statement dangerous. And about async code: Have fun writing bare metal code with that. Because, you know, your compiler will spit gotos anyway, and unlike gotos you write, you'll have little control over that.
