The newer technologies imo is even easier to access and more convenient to use, even for people living in third world countries than this older models. I believe it's fallacious to think that outdated systems would be more convenient for people. For example it costs nothing to be connected on the bitcoin blockchain network, you only need a smartphone, data and a bitcoin wallet.
I would add that older technologies are way less effective in general. So even a person from third world country with poor pc setup better be mining newer coins instead of older systems in order to get more profit
