Gammon can’t see the new world coming. Not a lot of people can. They’re extrapolating todays clown world into the future for forever despite all the historical cases of technology altering humanity’s course. He basically swaps the USD with Bitcoin in todays time and assumes human incentives stay the same.
If you can’t create new money or steal easily, humans will be forced to spend their time earning Bitcoin. Sadly, today not many people want to truly work for their wealth. So Bitcoin will compete vs the current system and over time it’ll get more and more people to adopt it and adopt proof of work. The current system will eventually implode.
