After two years of intense coding and hundreds of thousands presses on S while saving (⌘+S) it looks deteriorating:
It looks like something can be done about - VS Code has an option that probably can make it better: AutoSave.
To configure it just add click Code > Services and in User Settings add:
"files.autoSave": "afterDelay", "files.autoSaveDelay": 250
Everything you type will be saved immediatelly, which is a relieve.
