Actual operating life is often determined by the economic feedback loop which causes manufacturers to cut costs until basically all consumer products have roughly the same expected lifetime, regardless of the potential of the underlying technology.
* Or at least, the first millisecond after it starts using its normal operating clock, which might not be the very first millisecond
Which is why, despite being a huge BEV proponent, laugh when I hear people say things as "BEV are inherently more reliable due to having no transmission and less moving parts that could break". It might have been true in the early stage, that we're currently at the end of, but we already know that the reliability of a second-hand mid-range ICE car is what market has been bearing for decades, so we can be certain BEVs will be "value-optimized" until they are just as unreliable.
Anyone that has had to deal with a carbureted engine, or old school hydraulic ‘computer’ based automatic transmission is never going to extol their reliability or ease of repair.
Those also are doing 1/10th of the work (for things like automatic engine tuning, wear adjustment, on the fly power band adjustment, altitude adjustment, anti-pollution adjustment, etc).
The reason why people complain about modern cars is because computers have made it exceptionally easy to add massive amounts of new (and poorly tested, in many cases) functionality.
And even the equivalent of DRM.
If if you used current tech to implement the old feature set, and spent even a little effort making it open instead of DRM-ish, it could be even simpler and more reliable. But no one is doing that. Because it’s more profitable using it ‘for evil’, as it were.
