"ARM was born from Acorn's frustration with 16-bit CPUs that they considered as successors to the 6502, e.g. 68000, not the 6502" yes and no, were both right. ARM looked at a 16bit replacement for the 6502 and found the options of the 68000 not having the performance they wanted. They went to America and checked out the work on the replacement for the 6502 and concluded that they could just make there own CPU and so they did.
Had the replacement for the 6502 not been a one man team then history would be different now.
