Capacitors age because they are filled with liquid electrolyte, which dries out over time. Batteries age for mostly the same reason, and the chemical reaction slowly becomes irreversible. Those are easily replaceable. However, an integrated circuit is just a wafer of silicon. A piece of sand. It's going to take a long, long time for that to degrade. If it weren't for needing constant software updates and cloud connections to be useful, an iPhone could theoretically last a hundred years. "Tin whiskers" may also be a problem, but we are talking decades before you have to worry about that.
I don't think your theory about old things lasting longer because there is more mass to them is correct though. It really sounds like you are making that up because it sounds good in your head.
The larger components have more space between them... it takes longer for the "tin whiskers" to grow and become a problem. That and these old devices ran at higher voltages, so they have more tolerance to minor voltage fluctuations. Also, plastic does degrade eventually, copper traces can corrode, etc. Build quality matters, too.
