Other people spending money to figure out if an alternative idea will work is good for me.

Nothing, it just feels like a local maximum. Typing is incredibly efficient, so I don't think it is going anywhere.
There are plenty of ways of showing that in a certain situation non-text can be more efficient, so I believe there is a way to introduce non-text that can make the general case more efficient.
Any research at all? I'm curious: what it is that's unworkable about text in your view?
