article was cringy. RISC-V is among the newest being only a bit over a decade old. Yes it's based on an older design from the 80's but ARM, Intel, and AMD's are even older. You might say it's about the age or slightly older than MIPS...
Also, the 'RISC takes more code' is ambiguous and is a bit amateur talk. Yes, RISC binaries (ie, machine code) is larger, but the 'code' isn't. ie, it's an identical amount of code for an application on arm, risc, intel etc as the compiler handles the conversion to machine code. Saying it uses more code for risc is like... maybe correct in a very narrow scope of 'code'... but definitely not in the common vernacular. No one would say x64 requires more code than x86 for example, and x64 binaries are larger from the same input code.
I would not expect this from Tom's.
