It's also a consequence of constant R&D improvements. We can make appliances that last for 20 years or more, sure, but then when 20 years pass you have an appliance that is 20 years old and doesn't have any of that new stuff that came out in the last 20 years.
> new stuff that came out in the last 20 years. There isn’t really that much of this. Let’s consider an oven: Good temperature control: accurate, precise and reliable temperature sensors (e.g. thermocouples) have been around for a long time, as have switching devices that are plenty high speed to make an excellent oven. PID control would be easy with 1980 technology or current technology. Ovens with good temperature…
Typically you also get: more BTUs, better simmer control, easier repairability (due to construction design).
I'm not arguing it's worth the money (which is why I got my $15k stove from craigslist for $2k :)
