Besides not being monetizable I refuse to have some spy microphone in my home which sends all my conversations to Amazon Central.
The market penetration is therefore finite, limited to geeks and early adopters. I'm somewhat surprised they didn't consider profitability more thoroughly when they started with Alexa. It must have cost them $100 billion by now.
In my entire life I've only met a handful of people who had a "Smart Speaker" (Alexa, Google Assistant or HomePod).
People don't see any value in it. And some technically inclined acquaintance will probably point out that the thing records everything they say and sends it to Amazon.
The only thing that mildly makes sense is something like an offline version that controls the lights, heating etc.
