It has nothing to do with my faithI know you have great faith in a decentralized blockchain world, maybe it'll happen but I think it most likely won't. Guess we'll find out in 10 years or so.
I follow the developers and there's a huge shift into decentralized apps and blockchains. You mentioned alexa and google assistant.. maybe you don't know what Wolfram Alpha is or what they have been developing. The tech talent has already moved to the "decentralized world" so it doesn't really matter what you or I "believe"
I remember seeing high speed internet in a lab. Developers knew what they were building long before it rolled out and people started to "think" it would happen
Nothing is free. You can pay with your personal data and attention or you pay through an intermediary with a fee. You think you could pay the mechanic directly for free but don't realize what that implies. People definitely do have an idea what networks cost to operate.. very good ideasNobody has any idea what costs will be or how they'll be paid. Maybe some will be provided as a free connection service where you only pay your AR mechanic directly. You can speculate all you want, doesn't really do any good and I'm really just interested in the cool tech potentials.
Your ideas are way out there but there's lots of things being developed that are much closer to reality. You can even try the beta tests already.
