> Autocomplete speeds up code generation by an order of magnitude, easily, with no real downside when used by experienced devs

Strongly disagree. Autocomplete thinks slower than I do, so if I want to try and take advantage of it I have to slow myself down a bunch

Instead of just writing a function, I write a line or two, wait to see what the auto complete suggests, read it, understand it, often realize it is wrong and then keep typing. Then it suggests something else, rinse, repeat

I get negative value from it and turned it off eventually. At least intellisense gives instant suggestions ...
