Granted, but features have nothing to do with the issue here (wasting resources). Microsoft could have easily offered the same feature set with a different implementation. I have visual studio at work with 7 projects loaded and it sits at a comfortable 400 MB
If your laptop is your work system, it makes sense to have something powerful that costs a few grand. But then personally I'd pay a few extra and get a full featured IDE, why bother with text editors?
I'm a web developer. 90% of my work happens either in an editor, a browser or the shell. So yeah, VSCode's memory use doesn't really matter.
If you think Sublime comes anywhere close to VSCode in terms of features you haven't really given it a try. The code intelligence alone was worth the switch and perf-wise I see no practical difference in day to day use.
