Electronic Engine Control is YUGELY better than carburetors and mechanical ignition systems.
Safer too. (be careful about pulling out in front of a fast moving semi with a just started carburetor equipped automobile...)
Pretty much everything in a new or recent vehicle is ‘better’ and ‘safer’ until they get worn.
The issue is NOT what you described. The issue is what causes the more serious problems when degradation and failure set in.
You are probably familiar with dead or failing batteries, starters, alternators, water pumps, thermostats, etc.
But do you know what can happen when a sensor, ECM go out?
I don’t think you know. Study up and then come back.
Lastly, note that ECMs and all their sensors may fail long before other subsystems. Lots of cars have a lot of life in them except their electronic control system can fail early and the failure can happen in traffic under very dangerous conditions.
