sure, to this day you can find old stuff that is still working perfectly. but what you don't see is all the other stuff that has been discarded, thrown away, replaced. survivor bias at its best.
right now products need to adhere to safety standards, energy efficiency standards and have green certificates. if something breaks and just puts a minor scratch into you major lawsuits are going off.
in the past, you simply died in an accident (whoops, sorry about the electrocution or yes, our cars sometimes go up in flames).
