After tasting success with Kindle Amazon went full throttle with their hardware investment. They were optimistic about replicating Kindle success so they threw the entire kitchen sink at it. The division hired 1000+ in product and development in a matter of weeks. It was truly heady days but equally chaotic as no one had a clue as to what were they supposed to be working on. Managers and execs promptly built their empires took promotions etc.
However it was not clear to anyone how would they monetize. Whenever some lowly developer asked the answer was standard, Amazon’s model is to grow big first and then figure out making money.
But for the interest rate hikes perhaps they could have continued down the path, who knows.
All that said, if I owned any of Alexa devices I’d be planning on sunsetting them. They will put the entire infrastructure on a strictly lights on mode. So expect things to break on the edges, at first.
