If your 5.1 GHz (billion instructions per second) CPU had a 0.00000001% chance of failing at a given instruction, you'd have a 40% chance of a crash every second.
If a flight had a 1% chance of killing everyone aboard 10 million people/day * 1% = 100,000 people would die every day from a plane.
Newly-"AI"-branded things that I have touched work substantially less than 90% of the time. There are like 3 orders of magnitude difference, even people who aren't paying any attention at all are noticing it.
Software pretty much always "works" when you consider the definition of work to be "does what the programmer told it too". AI? Not so much.
That's exactly my point. You have to interact directly with the A.I. and be aware of what its doing.
