All those technologies were first developed in the US, for an American target audience, then exported to other countries. Other things also developed in the West and then exported: electricity, vaccines, et cetera. I agree that that's generally been a good thing.

The parent comment, however, seemed to imply that technologists should focus on "solving global poverty" instead of solving local problems. This represents a fundamental shift, because at that point SV technologists are attempting to solve problems they personally do not have experience with.

All the examples you provide solved problems that SV itself had- transportation, communication, etc.
