Sure, auto complete tools are great. What I'm talking about is being fast enough that even auto complete can barely keep up, combined with a depth of knowledge that allows you to make the wise strategic choices that cut out huge swaths of time and typing. Like the other day this other developer and I were trying to reorder columns of data and sort them by multiple groupings of aggregates in .NET. We were twenty minutes into what would have been hours of effort before I remembered reading about DataTables, which are in memory databases in .NET. We had our problem solved in a few minutes. No auto complete would have told me that, just careful, deliberate study.
