If you take your viewpoint then considering any processors (as opposed to using FPGAs is absurd), however the paper DOES mention processors, so why just that two?
To me it seems that the 'PC' platform is a toxic wasteland and ARM seems suspect for reasons described in the paper ( I had a conversation pretty much on the lines of the paper a few days before I first saw it ).
So the other processor architectures do seem potentially less toxic.
How viable is the 'oh noes the FPGA hardware / toolchain may be cunningly backdoored to work out I am making a GPCPU and subvert it' argument some people are making really? Seems a bit tinfoil hat to me.
