Is anyone working on anti-drone tech?

If they are, I can't imagine how they'd get an edge in a literal arms race against organizations with combined budgets of more than $1 trillion.

I don't see any reason China won't soon become a dystopian society with a combination of facial recognition and autonomous drones enforcing the will of the CCP.

The only way to protect yourself from that kind of situation is to try to prevent small groups from accumulating too much power (whether they're government officials, corporations, or even lobbyist groups).

I think a lot of projects exist specifically on using drones and lasers / dazzlers:

I believe some submarines are also working on submarine drones that can be deployed:

Although I think in the end, there will also be anti-drone drones, kind of like how you have fighter jets and bombers.

Quite a few. Anduril, Epirus, and others. Google “counter UAS” for companies that do this with a wide range of techniques from kinetic (hit it) to microwave (emp like).

"(and seeming inevitability of) weaponized drones" - it is not inevitable, it happened already.

Low-cost kamikaze drones seem like an unexplored but promising option.
