I think it has very little to do with writing and writing speed at all. Autocomplete is context sensitive documentation. Having to look away from the problem (at at web browser, another source file, or elsewhere in the same file) for hints about e.g. a method name, is very disruptive.

If someone would use autocomplete in the way you describe I don't think they'd be better developers without it. It's like saying we should all type with one hand since it makes us think more before we type.
