I don't think the entire space is dying. Amazon is having problems because Alexa has little benefit to them outside of direct monetization. They wanted people to use Alexa to buy things and no one wants to shop like that. So they have these devices and all this infrastructure to run people's kitchen timers, lights and play music. People will buy Alexa devices on Prime Day, use them dozens of times a day for years, and never make a dime for Amazon.

Apple isn't necessarily in the same boat. Siri isn't particularly good, but it does all those things well. Most importantly, it keeps people on iPhones and in the Apple ecosystem, which does make money.

You already have the phone and probably have a device that works with HomeKit so why not try it out. Next, you buy some new lights. Before you know it, you're controlling most of the lights in your house, streaming Apple Music and setting kitchen timers from your Apple Watch. Next time you need a new phone, you're not even going to think about anything else because if you change you won't be able to turn on your lights anymore.

Apple has a plan that works and Amazon doesn't.
