Until the next one.
I remember people who said a desktop itself didn't contribute anything to the "basic purpose of the computer" either but it's a heck of a productivity improvement.
'Bells and whistles" are often more useful than the cynic realizes. For example, they let you know when the train is coming and to get off the track ;)
You're either in a different world than I or you mean something more cryptic than I'm able to decipher.
Oh, come on. You're not seriously going to try telling me that you know what 'everybody' is doing in software, are you?
Depends on how one defines "truly new." Is Microsoft trying to invent the 'truly new' neural network emulator? Probably not. But that doesn't mean there's nothing 'useful' left to do with the 'old style' desktop operating system approach.
I don't know as it isn't my job to develop the next operating system. I'm busy building the 'next generation' tube amplifier, remember ;)
You and I have different standards then because I only need the new to be 'enough' more useful whether it's "truly interesting" or not and I wouldn't go back to NT (assuming you mean NT4) because I find the new 'bells and whistles' worth it.
