Well because it is. With a large codebase, things like navigating through a solution, automated code refactorings, intellisense, etc. can be done with IDEs. Do you all so litter your code with print statements to debug?
Are you just playing ignorant for fun? You must know that there are people out there hacking on the most advanced software projects we have such as the linux kernel or C compilers etc. and they don't all use IDEs.
And what percentage of developers is that? That’s about like the same bubble thinking of every developer works on the west coast making $300K a year that you see on HN.
And some people also still write in assembly. I also thought that any high level language was useless. Then I thought anything more high level than C was for beginners.
But I grew up and start being more concerned with making money and implementing solutions than having geek cred...
