@haitchfive I am reasonably enthused by RISC-V as being comprehensible.
The reference text book on it, The RISC-V Reader: An Open Architecture Atlas by David Patterson, Andrew Waterman is a blessedly short read and reminds me of the to the point simplicity of "K&R" (aka Brian Kernighan and Dennis Ritchie's book: The C Programming Language).
That even MIT created a course Xv6, which is essentially a re-creation of Lion's Commentary on UNIX but for RISC-V (e.g. https://pdos.csail.mit.edu/6.828/2020/xv6.html) to me at least, demonstrates that pedagogy is making an effort, across academic institutions, to put some oomph behind RISC-V as far as educational collaboration, with a lot less of the clandestine skullduggery needed by previous generations.
