I don't doubt it, but the same could be said of ML in general. Being in the right place at the right time counts for a lot.
I'm not sure how that follows. Folks have been using statistical machine learning techniques to analyze machine sounds for at least a decade in my experience, and probably since the 80s according to other comments here. Therefore, if you subscribed to a newsletter of articles like this one and tried to launch competitor companies, you wouldn't be second to market, but yet another in a crowded field.
Possibly. I was thinking along the lines of "look at idea, see if easily, reliably, and cheaply implemented, assess market & competition, decide accordingly".
Hell, even that could probably be automated. Hmm. ;-)
I think the Samwer brothers have some experience with the second-to-market process.
