Earlier quoted context omitted.
The sweet spot is 8GB for most people. I’d guess 80% 8GB/15% 16GB and 5% more. Even many types of developers are fine with 8. Apple collects a lot of metrics and I’m sure they know this well.
The M1 also means that Apple regains full stack control of its desktops and laptops. Their phones and tablets prove that when they develop both the main chips and operating systems themselves, they are able to eke out greater performance from lesser specs. Flagship iPhones always have less ram than flagship androids, but match or exceed their performance.
Most business users were fine with 4GB 5-6 years ago. Electron apps like Teams and Slack pushed it up to 8. The next tier are folks with IDEs, docker, etc that are usually 16-32GB.
