It's expensive (but not really, only compared to knives - a $500 GPU isn't expensive). It's probably mostly good in certain niches and using a $10 knife that's sharpened properly is probably 95% as good in almost every application, and using a $10 knife that is only reasonably well sharpened is probably 90% as good. Slicing stuff for hotpot or yakiniku or Korean BBQ is what I thought of when I saw the ad, while for a lot of things it's probably not worth it. But a lot of stuff is like that - good in a niche, OK elsewhere, and there's always a cheaper option that's more flexible and almost as good even in the niche.
I feel like hn is upset by the lack of marketing. This looks like a direct sales ad that you'd get on Facebook, rather than the hype research marketing that mostly targets the b2b types who mostly dwell here? The marketing isn't the kind of marketing they normally get targeted by, so they notice it's marketing?
I notice this on other forums. If marketing isn't slick and well targeted, people get upset and suspicious because it's marketing. But functionally, they're not upset because it's marketing (almost everything is), they're upset because it's not enough marketing, and functionally they want more marketing that targets them better.
