Works for something like PSN. I see cards for sale in local shops. They can presumably be used to claim some funny money in the service that you can pay with.
Steam could probably do the same, but would suck for a smaller operation.
There used to be some cash to BTC machines that would work with any service.
I would add "downvote posts with no useful content" to that. (Report if you know the community has had the sense to forbid that kind of posts.) That does seem to cause some people to flip out, though.
It might be able to give you tables or otherwise collated sets of information about multiple products etc.
I don't know if Google does, but LLMs can. Also do unit conversions. You probably still want to check the critical ones. It's a bit like using an encyclopedia or a catalog except more convenient and even less reliable.
I find it kinda of funny that he fell back to appeal to authority fallacy, though.
