You’re just saying, human-written software can have bugs.
That's pretty much exactly the point they're making. Humans create the training data. Humans aren't perfect, and therefore the AI training data cannot be perfect. The AI will always make mistakes and have biases as long as it's being trained on human data.
I don't think it would have to be any different than people getting a bigger tax return at the end of the year. Or like the HST rebates Ontario has been doing where they pay it out I think quarterly?
As it is right now, I've seen the occasional "tax return sale" because businesses know people just got paid a chunk of money and might be impulsive with it. I don't think this is necessarily a bad thing, the demand for everyday items won't change, and people will try and save money regardless of income level.
