On the other hand, the PPC Macs are at a complete dead end.
Indeed, the way tech and software are moving along so fast has essentially turned computers into throwaway items with lifespans.
You *could* upgrade a desktop with newer PCIe graphics cards, more memory and more storage, but at a certain point (usually by 8 to 10 years) the CPU will start to struggle to keep up with the needs associated with 8 or 10 years later. And ripping out the motherboard and CPU to replace them with a newer board and CPU after 8 to 10 years is practically no different from buying a new computer.
ARM SoCs used in smartphones are no different. Back in 2010 LG released the Optimus 2X, which ran on what was the fastest ARM SoC back then, the Nvidia Tegra. Fast forward to 2020 and that phone has all but completely vanished. There's a reason Cyanogenmod for the 2x ended at 10.1 (Android 4.2).
It's ridiculous to try and fight the "computers are now throwaway items with an 8-year-lifespan"; especially when new hardware with even greater power savings and performance keep being churned out every few years. Every hardware vendor is caught up in this, from x64 to ARM and even Loongarch. As long as hardware keeps improving, development SDKs and frameworks will include more things, and that will result in software becoming greedier.
The only way to put an end to this is to reach a point in hardware technology where CPU and GPU performance has plateaued and no more performance gains are possible.
