I learned along time ago not to trust technology.
That sounds like something a horse and buggy owner would have said about those new-fangled "horseless carriages".
The IDI engine is "technology" by the way. So is this website.
The problem lies in newer vehicles having a lot more sensors and computers, aka possible more points of failure.
If you have an old 100ft garden hose with 10 splice repairs, it's more likely to get a leak from one of them when being dragged around the yard than if it only has 3 or 4.
Old diesels like ours instantly have less points of failure for it "break down" (as in, stall while driving) since there's no spark plugs, no ignition system, etc. Nothing adjusts air flow either, something that's been around since I'd say the mid 1980s on Ford gas trucks, or at least early 1990s.
Our engines won't even shut off if the fuel cutoff solenoid fails stuck open. It's not common, but it does happen.
Owning an IDI with an E4OD means you can have all kinds of tech problems that ones with a C6s don't, but I see no one fussing "darn that E4OD tech! avoid it!". It requires a computer and a high failure rate tach sensor to operate properly. It's a fairly common topic on here.
My E350 RV doesn't even HAVE a tach sensor due to it's C6 and no tach clusters available.
Less added tech means less points of failure, but it also means things are harder to diagnose, adjust and repair. I can't wander into just any random repair shop that services diesels for timing check/adjustment because they probably won't have the experience and proper equipment to do it.
