Meh. When Apple let me use my HomePods as true rear speakers instead of limiting me to using two sets of stereo pairs I’ll know they’re taking Atmos seriously. Until then, they’re just toying with us.
I feel like there is a much higher chance of Apple creating their own proprietary spacial audio format than ever adopting Dolby Atmos. It's been well over a decade since Apple did anything that would even slightly enable their devices to play nicely with others. Imagine a world where technology worked seamlessly across devices through open standards regardless of brand. There was a time when that seemed like where things were going and a tech utopia was just around the corner. Unfortunately we all now know this didn't happen and instead companies started engineering proprietary ways of locking people into one system and then raising the price. There is a term for this phenomenon that I probably can't use here so I'll simply call it the en*poop*tification of technology. Replace the word in the asterisk and Google it for more.
