>A disadvantage of the RISC design was that since programs required more instructions,

It's important to understand that, while that was the case back then, today, RISC-V has best 64-bit code density, whereas best 32-bit is still ARM thumb2, with RISC-V being a close 2nd, and actually better with current B and Zc extensions, to be ratified soon.

This is achieved with very little complexity required in the decode, which becomes a net win if there's any ROM or cache in the chip.
