I have to agree on this one, there is no reason to believe that this
trend will not continue and I've lost every ounce of optimism I've
ever had in this area.

Besides, I'm having trouble believing someone who can't even get it
through his thick skull that even "M-x compile" in emacs gives a TTY
to the make process.  Yet he kept claiming the opposite over and over
again until I absolutely proved it to him, at which point he became
completely silent on that line of reasoning.

Someone who argues and behaves in that way is not someone I put much
stock in as far as implementing things in a wise or well informed way,
it feels more like a mechanism which is being forced and rushed ahead
without enough research or consideration.
