There is no way that all of this can happen within 10 years and how would the blockchain even begin to generate and provide a basic universal income for all people using it? All of the things you've listed take so much time to be adopted as change always does, I would be surprised to see any of them happen within the next 50 years.
We already develop Basic Income on Blockchain. We also have an MVP, soon we'll make an airdrop and lots of people will use it all around the world. We also already have partners who are ready to get our tokens for goods and services. Lets wait a little and see.
It's not a fear, it's inconvenient for us with a cashless world, no cash mean no fiats , no paper money. So what will you pay for your daily needs?
You'll pay with cryptocurrency. Why do you need fiat for it?
How do we not fear? The more advanced the technology then it also affects the price of goods and food in addition to the cost of education is also paid by using money, buy food for the family also use the money, basically everything should use the money. If anyone talks "I can live without money" i think it's just bullshit.
In a month we'll start an experiment, living for 1 month only with cryptocurrency payments. So you'll see, we don't need cash anymore!
