We have mathematically worked out near light speed travel, we just lack the energy requirements to test it currently. There are two methods proposed, one being riding a wave we create and the other riding under space(this one was way more confusing). The wave one would accumulate debris ahead of the wave so you aim at a planet then stop short propelling everything the wave has gathered at near light speed into the planet, instant obliteration. We are trying really hard to solve fission which is the only thing holding us up right now. Optimistically we might see a practical test in our life time albeit very late into our lives.
The kernel level access anti cheat is a pass for me, the company running it has had breaches before proving it isn’t secure and there have been instances where breaches like that allowed a bunch of people to get ransomware on their PCs. I would only play it on playstation 5 if I had one but there is zero chance of putting that on my PC that has all kinds of sensitive information like banking and personal ID stuff. Real shame because I loved the first game.
