> That is a pretty limited view of what blockchains solve these days. This reads like someone looked into Bitcoin once ten years ago and then applied that to everything that came after it. I didn't take it that way. I interpreted it as the author's personal list of "stuff I wish cryptocurrencies could do for me today." And, of that list, micropayments stuck out to me as a problem people have really, really wanted to solve for a long time, but just can't manage to make a solution work yet. Of course, the problem of micropayments effectively reduces to the problem of reducing transaction costs to a point where it becomes feasible to pay someone 5..10..50 cents without having to pay the payment processor an equal or near equal amount. But, that, unfortunately, seems like less of a technical problem and more of a social problem, which makes it a Hard Problem(tm).
