My thesis is that to justify their P/E and valuation Amazon has no option but to keep expanding into new business lines. A side effect of this expansion is lack of attention to their existing lines of businesses. For instance, Amazon retail UX and website has largely remained unchanged for like well over a decade and in fact gotten worse as they cram more and more things to sell within a screen. Same with AWS, quite a lot of highly asked features haven't been implemented for years now, and AWS console is showing its age. I have a feeling those Alexa* devices will not age well.
