Anyone seen this? Planned obsolecence or the light bulb conspiracy?

Modern things/gadgets are not made to last. The manufacturers want it to break and have you buy new stuff to keep their revenue going..

I was sort of "late to the party" and my oldest functioning (HP) calculator is the 28S from 1988, still with an intact battery compartment. Though, I've "retired" it and left it without batteries since the last replacement depleted a few months ago. I do have 6 fresh N-cells for when I want to use it.
I have my "mandatory school" (Ground schhol/Elementary school, 9 years "basic school" or whatever you call it around the world) Casio FX-82 from 1983, still with the original 2 AA batteries in it and functional.

My take is that, if something breaks "without reason" after a few years, I don't buy the same brand back.

My first Canon printer "died" after 4 years for no apparent reason, except that the "obsolecence chip" inside decided I needed to buy a new one. Nope, went to Brother. Then they stopped supplying ink to that printer. No more Brother in my house.
Let's see how long the Epson Ecotank printers last..
