If you can only hobble along with tool support, you never understood what you were doing. You don't have to rewrite everything from scratch, but if you can't, you lack the skills to use them effectively, and can't ever improve on them. And like I say, soon AI will replace those consumers.

Compilers are perfectly able to tell you the line of an error, you can use a debugger without the IDE, I run lldb or the Chez Scheme debugger all the time, but I understand what the tool's doing.
