> Apple was able to convince people it was worth considering arm
I'm not sure I'd phrase it this way. What Apple did was just great engineering and planning, along with a user focus. Also the fact that it was either embrace ARM or leave. :)
What I mean by that is, they launched their ARM/Apple Silicon line of computers and cut off their ties with Intel. They managed to get people buying the new ARM computers by providing an excellent user experience and incredibly good backwards compatibility with the older Intel binaries via Rosetta2. They also started rolling back some of their unpopular decisions of prior years - namely dropping all but USB-C ports and MagSafe. They also started providing Pro laptops without the dreaded TouchBar (yes, some people like it but I don't think numbers are much in its favour).
Then they engaged with the developer community and their users to help everybody transition.
