I remember using Terraserver (over dial-up, no less) in 1998 It was the coolest thing I’d ever seen a computer do. It was the first computing application I’d seen that gave a human a completely new capability that was not present in any way prior to computing.*

Funny how Microsoft had all this great tech and novel ideas and really never did anything with any of it.

*Computers made many things faster prior to this in my life, but did not give me a completely new superpower. Terrasserver did.
