2. Bitcoin transactions are irreversible and have inherent risks. If you want decentralized money, you have to accept this. Its a tool with a specific use case. Tether is the same as other centralized institutions like Paypal or Banks. They keep your money "safe" in a way. But you give up your freedom to companies, govt, and money printers. "Safety" is a scam, as Canadians found out this week

3. Regarding your comment about video phones in 2001. Just a timeline of when video phones became mainstream.

4. Not sure about yields of spinners, hydro/tidal/wind. I am skeptical since they haven't caught on in home installation market. Geothermal is possible on the scale of 1000s of users. You can study the use cases in Bavarian villages. The cost of energy is good if you can get the initial large capital. Was in the range of a couple millions of $ around the 2010s. They last for 30 years. If you find a open Geothermal vent at the surface, lucky you. But its rare.

5. Yes, formal education on a phone is not as good as a school. I was thinking of trades. I taught myself plumbing, masonry and home electrical via youtube. I think for uneducated poor people, those kinds of knowledge would be more practical and kickstart their earnings.

I just get more done and done better when I do less.

You are a focused person. I jump between things, even food and TV shows. I don't like doing one thing at a time. I also like to hear people talking while I do something. I get bored otherwise. This is extremely annoying for my girl, who like you likes to focus and work quietly.
