Honestly, the riots are probably fine, since anyone with no context would just see it as generic protest footage, or something along those lines.

Some massaging a few decades from now could tie it to the 2025 sanctuary city riots, or some other historical event instead of Jan 6 with barely any changes at all.

The Elon Musk reference definitely aged poorly, though, although having some diversity in views around historical inventors could be pretty interesting in its own right. Someone might hate Cochrane because he ended up with the credit for the warp engine, even though he didn't build it, and only did it for the fame and money, while others might respect him for his contributions to humanity, and being instrumental in Earth's official First Contact with aliens.
