IoT/smarthome has been a niche/fad going nowhere since day 1.
Smart speakers are commodities.
They dabbled in an EV project, canned it.
They've dabbled in AR with the VisionPro but really it's too early, if it will ever work.
AI is software not hardware.
Apple smartphones/tablets/watches have essentially killed 10x more hardware categories than have come into existence since.
They sell a lot of headphones I guess.
The only consumer electronics I buy now outside Apple are basically higher end niche hobbyist stuff in for example music or photography. Nothing that would ever sell at the price levels ($200-1000) or volumes (billions) to move the needle for Apple.
