15 years of supply chain excellence and the software running on that hardware quietly got worse every cycle. the m1 transition was so clean it made everyone else look like they were guessing. ternus thinks in tolerances and thermal envelopes - giving the keys to someone who's already pulled off the hardest platform migration in apple's recent history seems right.
To make the M1 transition so clean took a lot of software excellence...one can argue Apple's compiler / virtualization / software languages team is the best in the industry (grumbling from Swift UI developers aside...)
