Some things need to be expected to have a longer service life. I despise the idea of smart washing machines and smart refrigerators because it locks them into a fairly brief period of time. Something like a refrigerator should be designed for at least 25 years, especially a very well built one like a Subzero or Thermadore.

The idea of a super tech lover smart refrigerator that is expensive and needs to be replaced in 5-6 years. A really good refrigerator should be kicking for decades. I would trade smart features over long term robustness. Hell, I would give up cold settings, in unit water filtration, in unit ice maker an a ton of other shit if the refrigerator was built to last 40 years.

HVAC and Water heaters should also be 25+ year appliances.

I think with computers, it is reasonable that due to things like Moore's law they are not relevant forever. No one would expect a computer from 2003 to operate in today's world, and the computers 20 years from now will be the same jump in performance. I know people who feel the need to replace their computer every year or two, which i find to be silly. I use my computer more than they do, mine is over 5 years old and is still a total champion. I feel it will be rolling with the times when it is 8 years old. Computer service life should be like $400 per year. $2000 computer should last 5 years. High end computers that have very high price tags have their own cost structure, some $50,000 workstation I would not expect to last 100+ years.

I am not a phone guy, but my mentality is that a phone should last 1 year for every $100 spent on it. I use an iPhone SE2. I paid $450 or so for my model. I have had it for almost 3 years, I expect it to last until it is 4.5 years old. Granted, while the phone was $100 per year, the stupid phone bull was much, much more than that.
