1. Electric != electronic. Electrical engines have been a staple of engineering for about 200 years, about as long as ICE. Integrated circuits, on the other hand, have only been around for some 60 years, and while those are pretty reliable on the hardware side, we're still figuring out how to manage the complexity that they enable, and how to make software that's not shitty.
2. One anecdote does not a rule make.
3. "When you make a motherboard that works properly for more than 5 years, let us know." Maybe you should stop buying bottom-shelf. I've seen 10-year-old Thinkpads work like they did on the first day. And my current Asus notebook is already 6 years old and shows no sign of old age at all. Even the battery still holds over 80% charge.
