It's interesting that he wrote this as a user of the internet for 2 decades in 1995. So between 1975 and 1995, the pace of change was just not that great. Then between say, 1995 and 2015, a lot changed indeed. Faster connections, ubiquitous wireless internet, e-readers, fast laptops, smart phones, e-commerce explosion, video portals and streaming, social media, etc.

It feels to me the pace of change has slowed though. Maybe that's the way innovation goes. Sometimes in big bursts but mostly incremental.

I agree that small group conversations are probably the next wave of social media, because you need that circle of trust to be fully expressive.

If I had to guess, I would say we will perfect VR over the next couple decades and that we will replicate some of the brick and mortar experiences that way, but it will still not ever quite replace in person interaction. There's always going to be that uncanny valley between the cyber world and the real world.
