Meltdown and Spectre exploits are rooted in the nature of current CPU design. If you want to be safe, go build a RISC-V computer.

I don't think that's true. Meltdown and Spectre are sub-ISA issues, so you could have a RISC-V implementation with them if it handled caching and speculation similarly.
