Apple had Siri out and was in the lead with voice control, then they wasted it. I never use Siri, she is nearly worthless, but I do use Alexa multiple times a day. Amazon is Leading the voice assistant market, and Google is right on their heels.
Home automation was supposed to get better with HomeKit but arrived basically stalled. They announced all these partners and sold their products at the Apple Store. Then when HomeKit finally was ready none of those products worked with HomeKit. You had to buy newer versions that had some proprietary Apple chip in it.
Apple's cloud offering is confusing and hard to manage, also it doesn't work with other platforms besides their own. Amazon and Google both do this much better.
AppleTv is a great product but Apple can't seem to really work with partners to make it actually innovative. The TV app is a cool idea, but I've yet to find any reason to actually use it.
It just seems like they've been wondering aimlessly and dropping half products out there then never iterating and finishing them. Is there some other hidden project (car?) taking all their top talent? Is there some sort of corporate culture issue that has driven all the best and brightest brightest elsewhere? Is there a lot of mismanagement and mixed signals coming down from above?
