If you actually read his comment, I think you'll agree this was an accurate and fair assessment. I've worked with those kids who believe they're super smart and others are simpletons purely based on tool preferences.
As someone else mentioned here, the graphical merge tool in IDEA is extremely powerful. Plus keyboard shortcuts to all the main Git actions. It's overall more efficient. However I always use Git IDEA + Git CLI side by side.
Thank Garbage Collected languages. I just checked the IDEA config and found its maximum heap is set to 750 MB by default. You typically wouldn't need 32GB to run it.
You are delusional and immature. I've seen experienced Vim/Emacs kiddies like you really struggle to keep up with my productivity levels in IDEA with JVM languages. Doing everything at the command line doesn't make you 1337 and superior. The actual typing and manipulation of text is the least complex side of development. Most of my time is spent thinking, analyzing, rather than monkeying with text. However I use Vim keybindings in IDEA and get the best of both worlds. Efficient text editing + advanced semantic parsing at a level that Vim and Emacs will never achieve.
