It’s not mutually exclusive though right? For instance, google search has auto complete/recommendation to nearly any query. I use that when helpful and know when to ignore it as well and type in my entire query. (Genuinely curious as I don’t use these IDE features.)
no, not mutually exclusive, but the author had at least one anecdotal datapoint to suggest that people who relied on the IDE did not discover "unusual" functions that were better for the specific task
