Worth the RISC
Since macOS is just a cousin of unix, porting current applications to ARM will be a breeze. Bootcamp may or may not be removed however, as it relies on ARM ports of Windows for the Apple-branded CPU.
Recently, IBM open-sourced their new POWER9 CPU's (think PowerPC), and they already had 90% of all Debian Linux packages ported ofer in a few weeks/months.
I believe in 10 years, architecture (ie. x86, PowerPC, ARM) will be more of a preffered brand, except in very specialized applications.
