Around 2010 I met a former coworker for lunch and he told me how they were running serial stuff really fast. I told him I was also working on high speed serial stuff. I asked him how fast and he said 115 kilobit/s. I told him I was working on 8 gigabit/s or around 70,000 times faster. At that point I had not used RS232 in over 10 years. I have a friend who still uses RS232 for lots of industrial factory type stuff in 2024.
