The best software developers I have known are almost all insane typists.
How else might a single person hope to write, manage, morph or grow commercial-quality software whose source files run into the many 10s of megabytes?
Think through your code before you ever hit a key. Work in pairs to review code as you write it. Write efficient code.
“Insane typing” produces bug-ridden, bloated software (unless you’re getting paid by how many lines of code you produce). Modern dev tools automate much of the tedious text entry anyway.
