To say the problem is solved you must first state it.

Maybe your terminal problem is solved (mine is), but their problem may be different.

Would you tell people who made chrome to quit back then, because the browser problem was solved? (IE, Opera, Mozilla Firefox) Or maybe tell Google to abandon drive and Microsoft onedrive and all that smaller companies like SugarSync to drop it because Dropbox has "solved it"?

This also means that indeed your previous question is good: it'd be nice if the author could explain the use case and business case for his terminal, seeing that we have a number of others around. (Google explained why Chrome with a comics thingy and got me immediately). But your questioning sounded like the author was already in err.
