My family had a bunch of 80's appliances. They were terrible feature-wise like the washer would eat my clothes, the dryer was practically either stupid hot or practically no heat, and the fridge didn't have any defrost functionality nor water features. They broke down or were otherwise replaced in the 90s. They were replaced with units with far more features and were good until the 2020s, surviving a few moves. A few even got sold in the end as needs changed.

My current kitchen has a microwave that's from the early 2000s, it works fine and has exceptional even heating and top notch auto sensor modes. The 1980s one we had was a total hunk of junk that constantly had failures, wasn't as powerful, didn't have any sensor cooking modes, and performed very poorly at cooking evenly. The other microwave from the 90s ate fuses for breakfast and had massively unreliable sensor cooking modes.

So for me, practically all my newer appliances are way better than the old ones and have still often lasted >10yrs. Anecdotes are anecdotes.
