Fred, let me enlighten you.

New cars have electric fuel pumps, therefore all cars with mechanical fuel pumps were unreliable.

New cars have 12 volts, therefore all cars with 6-volts were unreliable.

New cars have electronic ignition, therefore all cars with breaker point ignition were unreliable.

New cars have disc brakes, therefore drum brakes are unreliable.

New cars have electric wipers, therefore vacuum wipers are inadequate.

Etc. etc.

Seriously though, I can see one exception; for cars that are driven perhaps once a month or even less, an electric pump pushing thru the mechanical pump and used just to prime the carb has some merit. Perhaps also as a backup for folks who live in VERY hot climates or high altitudes and might be subject to vapor lock. But in both cases, I'd never rely solely on an electric pump, it should be used briefly to push thru the mechanical pump on those rare occasions where it's needed. Among mechanical pump's several virtues is that they tend to give early warning when they are beginning to fail, electrics simply stop.

But Fred, don't you also think this type of thinking is the product of the generation of cars which people grew up with and understood? PS - and perhaps coupled with a lack of curiousity in understanding the older systems.
