This to me is one of the really big but less talked-about implications of Apple Silicon. 12 months ago - before M1, before Big Sur, before the Mac Pro reboot, before the MBP 16 - the Mac had atrophied. Hardware quality had gone down, the software felt neglected (the UX update in Yosemite felt like a half-hearted skin). The Mac felt like a side-project. It felt unimportant to Apple; there was speculation that it might be turned into an iPad with a keyboard, or be dropped altogether with the all the new energy surrounding the iPad Pro. Apple seemed like it might just exit the workstation business completely.
In the past year that trend has been turned on its head. First they fixed the keyboard and refreshed the MBP form-factor and internals. Then they came out with the radically-powerful (and expandable!) machine that pros had been asking for for years. Then, most importantly, they came out with a huge financial commitment to the future of the Mac, making it a seriously compelling workstation again, and the cherry on top is a new UX that, for the first time since OS X (nearly 20 years ago!), looks like it was designed cohesively from the ground-up. No matter how you feel about Big Sur's design choices, it shows that Apple cares about the Mac again. And they're just getting started with the new silicon.
For an ecosystem that asks a lot in terms of commitment, it is hugely encouraging to see such an unambiguously renewed focus on this product line.
