I don't see this as baseless to be honest. As someone in the camp of "technology always has political implications", one of the interesting trends I've seen with tech is that most of the benefits go to the rich first. In some ways yes, that makes sense. The problem is when they never transition to the whole population effectively. Take subways, a well-defined technology at this point. Pretty much every city you look at, there's a minority community without proper access because the city sees the cost as not worth it to build the additional line or pay for service. The Orange Line and Roxbury come to mind in Boston, who instead got a talked up bus system to replace a line moved out of a minority community.

When you see a technology like this and think of the benefits, considering who gets those benefits is a big part of the value of the idea practically. To me, it's nothing against the ideas technological merit, academic impressiveness, creative ingenuity, etc. It does reflect what ideas someone like Musk is focused on though, and I don't think bringing it up inherently means they have an axe to grind. I think Elon is doing a ton of good and is one of the few SV bigshots that deserves hype (looks sideways at Peter Thiel), but we should have realistic views on who his projects are exactly helping both short and long term.
