If it were tech problems we wouldn’t be drinking clean water, driving Teslas and eating fancy food now would we? These are more or less solved issues. Now what we have not solved is how to share our toys.
Of course, tech could help to lower barrier(s), making access so cheap even “they” can have it, but the fundamental problem here is: why do “we” have “it” and “they” do not?
These are deeply political problems with exceedingly thin ties to technology. I feel focusing on tech distracts from the true issues which are again political and cultural, related to, say, the economy and its underlying philosophy itself, education, geography, history, etc. I don’t know where exactly tech ends up on this list of major factors, but it’s not on the first few pages.
Interestingly I think it is the diplomacy and activism that enabled the resources to open up and drives activity in tech that then eventually winds up where it needs to.
