ARM instruction set has not changed very much at all since then and is in many chips in nearly every device. More are made than any other design.
She is also trans and transitioned in 1990s. Being a cis woman in technology can be frustrating even today. She was a trans woman in UK tech in 1990s.
This is a innovator in technology. Not Jobs, not Musk, not Gates. Wilson created the CPU design which is cheap, simple, efficient, strong, and has become universal today.
Mostly correct. Having a larger set of instructions do not make a CPU faster however. The same operation is being done in each case whether there are 5 or 1 instructions being sent. The instruction just takes multiple cycles on the CISC design. There is a disadvantage to this though, as the 5 instructions could be reordered by the CPU to be more efficient. In modern processors this does not matter though as there are not true CISC processors outside of very slow embedded systems any more, and the modern x86 CPU turns the 1 instruction into 5 internally.
