Predictable Apple-troll is predictable.
Apple did not invent everything. ARM was a well-prepared platform for general purpose computing long before Apple showed interest.
"In the late 1980s, Apple Computer and VLSI Technology started working with Acorn on newer versions of the Arm core. In 1990, Acorn spun off the design team into a new company named Advanced RISC Machines Ltd.,[30][31][32] which became Arm Ltd when its parent company, Arm Holdings plc, floated on the London Stock Exchange and NASDAQ in 1998.[33] The new Apple-Arm work would eventually evolve into the Arm6, first released in early 1992. Apple used the Arm6-based Arm610 as the basis for their Apple Newton PDA".
And for over a decade they have been investing in ARM (for iOS uses), and later inventing and designing their own ARM CPUs, so there's that. Plus lots of work on LLVM for ARM.
DEC approached Apple wondering if they might be interested in a high-performance ARM, to which the Apple engineers replied "Phhht, yeah. You can’t do it, but, yeah, if you could we'd use it."
