There’s also a lot of hype, that AI will create evil robots with super-intelligence. That’s an unnecessary distraction. Those of us on the frontline shipping code, we’re excited by AI, but we don’t see a realistic path for our software to become sentient. There's a big difference between intelligence and sentience. There could be a race of killer robots in the far future, but I don’t work on not turning AI evil today for the same reason I don't worry about the problem of overpopulation on the planet Mars.
