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.

Haven't you ever come back to a piece of code from a month ago and had to reacquaint yourself with it? (I know I can't be unique in that... ;) ) We cram an awful lot into our heads as devs, there's no room for things we barely use from a month ago.

To you, the shell may be perfect. For someone else, it's a severely antiquated method of input that was outdated after Windows 3.1.

I love me some shell, but that's you and me. Not all devs.

Edit: reminds me of CPR class. After a month or so, you better brush up lest you actually need to use it!
