It's 19 years since the iPhone came out, that's almost two decades. 19 years before the iPhone was 1988. Things from 1988 definitely seemed dated in 2007. In fact I think style/aesthetics change is now getting slower and slower. Anything within the last 10 years looks like it could have been made today, since the image resolution / quality doesn't significantly change in such an obvious way. Throughout the 90s and 00s, it felt like things were constantly changing year to year. Totally different mindblowing graphics in games in each release, new OS features, digital cameras, cell phones (at all), then color screens on dumbphones, PDA, smartphone etc. etc., any Internet at all, then broadband etc. It subjectively felt much more rapid than today. The only exception is AI today, but even that is a different feel.

The rate at which AI is accelerating seems the same as other big inventions.

Some examples:

- Tim invented the WWW in 1989, but I'd took until around 2000 (10 years) to go to the web we now know with Streaming and Social Media.

- The first big mobile success (Nokia 3310) was in 2000, the 'end-stage' phone (iPhone 5 or something) was also 10 years later.

- Google Deepdream was in 2016, to "Will Smith eating spaghetti" in 2023, to now AI generated video literally unrecognisable from real.

I think we will be seeing some 'end-stage' AI in the next 5 years too, where the rate of improvements will sharply drop.

Robotics will probably be next? First company that can create an all purpose robot.
