At some point you have to accept that there is no one in the linux space incentivized to create a modern desktop experience, much less laptop power optimization comparable to a “vertically integrated” player like Apple.
I would love to get Apple hardware and battery life running Debian. Maybe Asahi will make it happen. In the mean time, I’m enjoying 99% of the things I like about Linux, with none of the massive pain wading through forum posts trying to figure out what bitman97 did back in 2015 to get their backlight to work with the Debian stable kernel
