In my experience, they had a lot of stuff working well in the first few years they rolled out the home voice assistants - Alexa, google home, etc. But for whatever reason, they've spent the last eight(?) years silently breaking things that used to work. Stuff like audiobook playing, music alarms, or even messaging people.

Once they started seeing useful (if niche) functionality as a cost center, there wasn't really a world in which these could usefully exist. Their big bet now seems to be that LLMs will lead them to profitability - but whether that's from increased data harvesting, cheaper integrations, or because it'll be useful enough to charge subscription fees, I couldn't tell you.
