As a quote from the Swedish Pentax Service "We have never seen a worn out K-5 shutter", but I'm sure they have seen loads of burned out or physically harmed electronics causing failure.
There's sadly no reason for manufacturers to make things more durable than passing the line where consumers would likely be okay with just upgrade. Look at the old cameras and you can easily see that they worked under a different philosophy, something more like putting pride in the actual manufacturing of products. Now cutting costs and planning for the right amount of longevity seems to be more of the philosophy for consumer goods. It's not like it's hard nor expensive to design most electronics to last like the use of higher grade capacitors, but still that is not done.
If electronics are more durable than mechanics why isn't it true when checking consumer electronics then? If electronics are supposed to get more durable with time, why do modern stuff die before even old stuff that keeps going strong? I simply don't believe that they will up the electronic design when it comes to durability faster than the specs sheet keeps improving so I don't see any increased longevity. The mechanical stuff has to be of a certain level to be reliable, it's easier to cut corners with the electronics.
