Its true that TBI is a more crude setup, but essentially it is basically the same thing. Got a computer that controls injectors to maintain a proper mixture, with a few sensors to provide other information to base that mixture on such as the engine temperature (if its too hot, richen the mixture, too cold, lean it out) engine vaccum (we all know that a well tuned carb produces more vaccum than a badly tuned one, same goes for a TBI, the ECM uses the MAP to generate the best vaccum), throttle position (no brainer, lol) knock sensor for timing, etc.
Really quite simple overall, esspecially compared to some of the newer EFI systems.
I dunno, I can see how EFI of any sort is typically not nearly as nice as a carb on a hot engine designed to race, but as far as ease of use goes, it really cannot get any easier than occasionally changing an easy to access sensor / actuator and turning the key to start it up

Just need to be able to diagnose the issues that do come up (and carbs can be the same way, gets jet stuck etc)
I guess, its a generational difference. I was raised with electronics, so its easy for me to figure out. I can diagnose most issues with a fuel injection system, but when it comes to a carb, I am as in the dark as you are with EFI, lol
