Mentioning Kessler syndrome, especially in the case of Starlink LEO satellites, is the classic midwit signal.

> ...space junk orbiting between 400 and 1,000 kilometers—where most low Earth satellites operate—is already unstable. And between 520 and 1,000 km, the researchers found, debris concentrations are at or near levels that might sustain runaway growth.
With regard to starlink:
> Starlink satellites orbit between 540 and 570 km altitude in multiple orbital shells
I'm sure it'll be fine once there are a million 8-/
I would have to say, elon fanbois are the most classic midwits...
