It's not crippling, it's annoying. I can code without an IDE just fine, I just don't want to. It's too slow and you end up doing a lot of very repetitive and boring tasks. Modern IDEs, much like type systems, help you avoid whole class of errors. Why type a method name, with the risk of typos, when with 3 keystrokes it's filled for you and provably correct. Same for renaming operations, function/variable extraction, etc. Also, code navigation. Large codebases are read a lot more than written. And code is not read like a book, it's more like traversing a graph. Do dataflow analysis, find usages, analyze hierarchies, etc.
