I wonder how many conversations there were in the 80s or 90s about how video on demand would never become mainstream because of the bandwidth requirements.

I think that physically going to _any_ special destination such as for tourism may be on a steep decline in the next few decades. VR glasses and goggles will be coming out that are very lightweight, comfortable, and convincing. We will also have eye tracking and eye contact in VR. There will be more advanced, faster more realistic 3d scanning of locations. There will also be the ability to "live scan", transmit and faithfully reproduce people moving around in an area. This will take advantage of advancements in graphics and AI.

Haptic glove technology will improve.

The conversation will be something like "remember when you had to actually _travel_ 5000 miles to see the Sistine Chapel or the last Blockbuster?"
