Yeah I have been using VS for nearly a decade now but I've never 'bricked' it. Sure, sometimes installing new versions alongside old versions could cause issues. But that's a managed process that one team member would do before the whole team migrated and any issues would be worked out during that stage. (one of our old upgrade steps was to install 2015 before 2013 because doing it the other way around would break something in 2013; 2013 still being needed for some projects). I have never been in the situation where the entire company (or even entire team) was locked out of their IDE.
