You have a Time Displacement Teleportation Device (or two). Your computer is making split-second decisions, & it knows an outcome or event 50µs from now and can correct decisions. You now control something; 50/50 decisions are now 100% success for you. With two time pumps 1:3 odds become 100% assuming both computers are given the same three choices with identical outcomes. And so on. In fact your odds have at least increased for every unknown decision. This easily turns into profit, but not at a casino or lottery - not enough time for a human response compared to this question. It’s a split-second decision.
These refrigerator-sized time pumps are commercially available and are changing the world with inexhaustible energy. But, you just “repurposed” a time pump to teleport your computer information back to itself in the very near past, so it can make a precognitive decision. This decision will greatly change your near-future, middle class average life, and you can do it repeatedly but not iteratively (you can’t send it back to the same decision moment more than once). Also, your modified calibration of the pump increased the jump time, but unfortunately only allows you to use it 3 times per day within a 30 second window, at a time determined by the position of the earth that day.
You start thinking about what important information you can know in 50µs:
can it guess a password or PIN? No.
Can it make a go/no-go decision based on an immediate outcome?
Can it hack a multiple choice computer test? Maybe but not online. Network lag is a big problem.
Can it place a winning stock trade? Unlikely.
Can it bet on an online game? Network again!
Can it improve Deep Learning algorithms with minute precognition?
