If there's one scenario where I'd dread autocomplete-based/chorded typing is when coding or writing on a terminal. My coding usually comes _after_ some consideration about I want to write, and having to tack an additional "let's proofread what the software thought was close enough" step on top of that would make it seriously annoying. I already have an expansion plugin on my editor that allows me to insert potentially massive amounts of boilerplate for me if I happen to need to, and I already trust it.
