The sad reality is we've solved many of computation's problems, and don't have much of a utopia around as perhaps expected in solving them.
Macs in the 2000's had productivity apps that were needed, fun to discover & to try out:
* Growl for notifications
* AppFresh for automatic downloads
* Quicksilver for file/app search
All of which has been solved by the OS.
Web 2.0 solved connecting with friends and strangers around the world, as well as many other problems, by FAANG+.
Web 3.0/VR will be 2.0 on steroids, which too eventually will get boring.
As big of a nerd I am, computation I'm finding can only go so far in satisfaction, thus eventually "stagnate."
