I vaguely remember 4chan figuring out something to do with which was the control and which the variable and deciding to spam solving the control correctly but the variable with some kind of nonsense (knowing 4chan probably a slur) until the system got enough confirmation that it got moved to the control group and would accept I it there
One thing to consider, assuming the red one is mental time travel (which is the only way it’d really be at all useful), you’re essentially murdering everyone who exists from your subjective present to the jump point to replace with at best very similar clones and possibly no one or completely different people. Then you have to also assume the timeline isn’t fixed and you can actually change things, and thus contend with butterfly effect causing divergence making your knowledge less useful. Sure, little changes probably won’t impact things on a global scale for a while, but once you start doing big things like investing or preventing terrorist attacks or something that could cause major divergence. Ethically any kind of useful time travel should be limited to “World is already wiped out” scale scenarios where the alternative is worse.
