Yes. I think it will always be useful to have a method of precise, non-verbal communication produced by the rapid trigger of physical switches in a particular order. The physicality of the switches is actually quite important to this behavior. So as long as we need to type, I would expect hardware keyboards to be desirable. We may not need to type, however. We might dictate or think our words; however when absolute precision is required, I'm pretty sure a text-level voice interface is always going to be pretty tough to do well.
