My first full time professional job (1976) involved writing assembly language for the TI 960, a process control minicomputer with a 64K data address space and a different 64K instruction space. At first, I just thought it was odd to make the hardware more complex by having two address spaces. However, this prevented a common cause of difficult to find bugs in asm programming, and I came to appreciate that hardware could make programming safer. Hardware architecture, programming languages, and compilers advanced rapidly, but safety always seemed to take a backseat and was left up to the programmers. I’m glad to see developments like Rust and I look forward to using it for a real project soon.
