Blockchain will make a big difference in extending the internet's capability. It doesn't have to be used for cryptocurrency - a block could represent anything. So it might even move us back to bartering "I'll give you three dozen eggs for that lumber" kind of thing, with the details of the transaction stored for posterity in a way that can't be altered.I used to have a minimum of two mobile phones when I was in the UK. It's very difficult in many lines of work to operate without one.
I've had computers (3 here atm) for a very long time but they weren't connected to the Internet.
I've never owned a TV.
I'm not at all anti technology and I'm quite good with most of it although the so called smart phones would have me guessing.
If the Internet fell to bits I doubt I would miss it much. It would make keeping in touch with my daughters and family more difficult but otherwise the Internet is much like TV; a great idea not reaching anything like it's true potential.
Not sure if that's what you were thinking when you expressed the view that its potential in unfulfilled as yet? It's still quite new and I daresay it will take us a while yet to truly leverage it's potential.
