That said, you can tune a carb with a screwdriver. You can't tune an ECU with a screwdriver. So you can make a barely functioning carb vehicle run again relatively easily, for years, with minimal parts required. Usually it just needs some cleaning if it sat too long. Compare that to a car that requires the entire electrical system and computer to function to even start moving gas from the tank to the injectors sometimes, a vehicle with a carb can be built like a lawn mower - simple fuel system, basic electronics, and you can make a reliable enough vehicle that's intended to be repaired.
Fuel injection systems are pretty reliable by now.
Like sure, you are not gonna tune them with a screwdriver, but in exchange it more or less just operates the engine on the best available point all the time.
