plus 2 more hands for the keyboard.   Maybe another to hold the coffee.

saying "no"  or "back" or "up"  is easy/quick/ probably reliable.
Eye-tracking is an old technology, but doesn't seem to be out in the

Most people have either experienced no significant speech input, or
have had relatively poor experiences... the most reliable versions
require some speaker-specific training and a restricted vocabulary.

It is possible to have a large vocabulary or speaker independence.
It is hard to have both.  I'm not sure that brainwaves would be a
step forward.
