I agree that unless the point of the question was more of a power move to show he's not an idiot and that they shouldn't try jerking him around, the question doesn't seem particularly useful.

The action of creating Libra could be interpreted as an attempt to undermine US federal currency. Facebook is the first company with enough clout to actually succeed at widespread cryptocurrency adoption to attempt something like this. I think there are bigger issues to deal with than quibbling about languages and release cycles. I know that the congressman's unspoken question is really whether Facebook has considered the security ramifications of allowing foreign nation-states to meddle directly with our system of currency like they were able to meddle with our news media, etc. But we all know that great programs can be written in terrible languages and terrible programs can be written in great languages. If the congressman is thinking what I think he's thinking, I wish he'd come out and say it instead of beating around the bush.
