Who's "we" in this context? Because just below you, HN has comments from willing donors.
My point being that while there may still be a market for SDR, there's a broader market for speaker-independent recognition (SIR) simply because people want the tech to just work rather than feel like they messed up training the device when the device can't recognize them.
Using someone else's voice assistant is also a legitimate use case, especially if it's used to control music, lights, blinds, AC, car functionality ... that absolutely requires solid SIR.
I think this can be viewed as a marketing and UX problem, sort of. It reminds me of the Wii Amiibo - people actually paid money to train their AI bots because of how Nintendo designed them. Not sure how many people, but a reasonable enough segment of the market that Nintendo thought it a worthwhile investment anyway
