Earlier quoted context omitted.
I'm with you in the first sentence, but the second doesn't make sense to me. All 4 combinations of (not-)solved-by-tech and (not-)caused-by-tech are possible.
Can you give a concrete example of caused by technology, but not solvable (in principle if that was what you meant) by technology? I am having trouble coming up with one.
I think that's pretty far out from the sort of thing that people are thinking of when they talk about things you can and can't do with technology, so I think it's more sensible to just say that the category is empty.
