>but debuggers/profilers are incredibly useful and important, and it’s essentially malpractice for a developer never to use them.

Just wait for the moment you need to write code for an embedded platform that doesn't have a debugging mechanism.

I've been programming for more than 30 years. Funnily, I used to use debuggers A LOT (in Borland Turbo C++ DOS "IDE" times, Visual Basic, Eclipse, Netbeans, Adobe Flash Builder, etc). But nowadays I seldomly use the debugger, if at all.
