It's interesting to think about the sorts of things we could do if we had low level control over our hardware. Unfortunately things seem consistently headed in the opposite direction.

- colejohnson66 2y agoRISC-V wouldn’t help here at all. There’s nothing about RISC-V that prevents a CPU manufacturer putting in custom instructions and not documenting them.
- seanw444 2y agoI understand that, but my sliver of hope is that since it's an open architecture, there will be manufacturers that make very hackable versions of it.
