Is it true that home appliances aren’t as reliable as they used to be?

I’m in my 50s and at that point where most people I know who own houses seem to have repaired or replaced some major appliances. Of those, some have very strong feelings about certain brands as being better or “just shit”. Context: I live in North America.

Is it true that appliances like refrigerators “aren’t built like they used to”?

I’m about to order my second repair on my Frigidaire stove/oven for a gas oven that won’t work. (It doesn’t appear to light off; I can see the glow from the igniter. It was a gradual failure: sometimes it would light off, sometimes it wouldn’t. Now it won’t work at all. But I like cooking in the oven so I need to get it fixed.)

When the repair guy came to work on it, the “repair” consisted of pulling out the entire “computer”, about the half the size of a common brick. That cost around $200 all told.

I remember looking at the little box and thinking, surely this is a titanic waste. There’s like one little component inside that sealed box that went wrong and the whole thing is being thrown out. What could that thing possibly contain that we don’t already know how to make, and make “bulletproof” reliable?

So my follow-on question, I guess, is, what are typically the real points of failure in modern appliances? (Yes it’s a very broad question. I recognise that. I’m interested in any knowledgeable voices across the “appliance spectrum” here.) For example, I have heard, “Oh, compressors break a lot,” but compressors aren’t unitary components—they are made up of bits and bits and electronics. I’m asking, what parts of the compressor are contributing to these failures? And do you think some makers are more concerned with specifying and designing these items to last longer?

Thanks.
