I completely understand the position of the person you replied to. One video outlining it is here: https://www.youtube.com/watch?v=Q3XuFr7rw84 . Many people disagree with it but I think thats because they don't imagine being productive without auto-completion.
> If I were a boss of a company and saw one of my employees do this, I would seriously reconsider their employment. Purposely limiting yourself has no place in development.
If I was a boss of a company I would try to judge people based on some objective measure, rather than subjective opinions about how one should be doing things.
I write in languages with and without IDE. With autocompletion, I'm more productive than without. Even in shell I prefer to use autocompletion or two panel file commander, because it lowers burden on my brain. I don't need to spend brain cycles on correctness of typed code. I know names, I type fast, but with Tab it even faster to type, and less error prone.
For example, when I started to use Rust, IDE was not available, so I used plain text editor for about 2 years. When I switched to halfbaked IDE, my productivity is raised because of autocompletion and error checking on the fly.
