> "I suggest that the security mitigations for AMD64 are pretty good, given the amount of eyes over them and automated testing for checking for their existence. There are still attacks like rowhammer that essentially don't really have any mitigation techniques"
Row Hammer was a good one to mention: I don't think risc-v has anything to do with it, as it targets the dram, and I suppose the risc-v beagle will have dram too... maybe risc-v with sram would be super secure--but sram chips seem to be measured in KB, and a MB chip is a huge one; 500 hundred of those would sure take up space and dinero...
You're right about low price -- I go through laptops like boots: lucky to get a couple of years out of em; I stopped using expensive laptops as soon as I was old enough to have to buy my own -- currently on $200 boxstore lenovo ideapad with amd hybrid cpu/gpu -- Don't need expensive laptops, because if I need to compile a linux kernel, or qt5, I can rent cloud resources by the minute: provision a linode with 64cpus, do the work, save the binary, and then delete the linode only having paid a few cents per minute--and when I do that, I have more processing cores than any expensive laptop... cloud virtualization really changed the game
