I had the thought while grumping at my Alexa. I say the same phrase every day, and every day there's a 50% failure rate. I keep looking for phrases that it can understand better than the ones I've cycled through, but they all suck.
But Alexa, as shipped, was pretty great. The fact that it hasn't seemed to improve at all since confounds me. The reports of the high body counts in the division surely attest to the lack of focus or interest in core Alexa skills. All those product and integration priorities were on the wrong product stack layer.
Same with: iPhone typing, Siri, Tesla software (and beyond FSD -- the only thing that seems have happened in the 2 years I've owned my vehicle is the addition of Apple Music), Apple Watch, etc.
