I find this statement really odd. The reason why people liked RISC chips is because, at one point, they had faster clock speeds that CISC chips. However, since then CISC chips have become significantly faster, run at a higher clock frequency and can do more with each clock cycle. Hence anything RISC is in the past.
I worked in the VAX/Alpha world 20 years ago. That architecture was dying then, and is now all but dead. There is still a local steel mill that uses Alpha processors. But they only use it because they haven't yet rewritten all their old Cobol and Fortran.
I get the argument that cloud computing means fewer tech jobs. But companies will still want some knowledge in house. But maybe not forever.
