go look at some forums for cheating, and you will see that they really do not work very well. it may be a cat and mouse game, but there is constant reverse engineering work and development being done (some of which is even paid work for paid cheats), and there is pretty much always a solution for new anticheat measures that someone finds.
the only unbeatable anticheat is a server side one
i dont think its realistic to have reliable anti drone defenses.
i fly an fpv drone (the kind used by ukraine), but for fun and without explosives, and they are so small and manuverable that it doesnt seem super doable to hit them with a net or whatever. jamming would work, but they can just use a different frequency, and gps spoofing is only a problem for autonomous drones.
i dont know enough about lasers to judge them, so maybe thatd work, but as an example of how extreme drones can get, there was a guy who built a little quadcopter that flew up to 40,000ft. its a hard problem
archive team runs a distributed effort to scrape and archive all of reddit, it gets uploaded to archive.org, so at least a large amount of it is accessible through there
Server side is beatable as in, you could inflate your skill to that of a professional player.
The optimal serverside anti cheat would be able to recognize what gameplay is human level, and what gameplay is impossible or very unlikely to be human, and make punishment decisions based on that.
Then, the best cheat would just be almost perfectly simulating a pro player, and at that point the cat and mouse game of anti cheat and cheating would be far far less relevant.
Something like blatant tf2 spinbotting, or scoping someones head through a wall right before peeking them in r6, are absolutely detectable serverside with heuristics or machine learning models or etc, and that should be worked on rather than embedding some spyware into my uefi firmware or whatever.
