I2C buses still tend to turn up in modern computers for running various low level components. Stuff like allowing the CPU to talk to power management systems, controlling fan speeds, RGB lights etc I don’t think there are any high bandwidth multi-drop busses anymore. Electrically multi-drop busses don’t make it easy to ensure the needed signal integrity for high speed busses.
