I wish.
Electrolytic capacitors seem to have a functional lifespan of about 10-20 years, transistors do wear out, electromigration is a problem in chips in the "hundreds of years" span discussed, and there are all sorts of other interesting failure modes of "solid state" electronics that mean they're not going to last hundreds of years without some pretty massive heroics - and that's when you can repair it at all.
