If you went back in time 50 years
And tried explaining the concept of the internet to people, I bet most would think such a thing would no way be possible for a long, long time, certainly not within theirs on their children’s lifetimes!

More than 50 years.
Even so, we are talking about something which is conceptually quite clear.

It's not a lack of imagination, it's a yawning chasm that separates the idea from our capabilities.

Just because you can think if it, doesn't mean you can ever do it.

Star Trek? The chances of humans ever actually getting out of our own solar system are pretty much zero. You can trot out the 'we don't know what we don't know' argument, but the truth is, what we DO know tells us it's never going to happen.

Virtual reality even approaching the point that we are unaware of it is never going to happen. The only way to do that is to trick our own minds into acceptance of a lesser reality.

"The machine Stops" was written by E M Forster in 1909 and is surprisingly familiar to a modern internet user, well worth a read.
