I know you put launch in quotes, but just to emphasize - the internet was launched much earlier than 1989 in terms of the technology. The base technology was worked on in the 60s and 70s, and things like email were already in use in the 70s and early 80s.
Of course, digital cash has been worked on for many years too, but if you compare the bitcoin whitepaper to, say, the TCP/IP RFC, then you'd expect AOL-comparable bitcoin usage in 2030, more or less.
If you compare this underwater spacetravel whitepaper I wrote in 2008 to, say, the TCP/IP RFC, then you'd also expect AOL-comparable underwater space travel usage in 2030, more or less.
