If you have that option. Not sure if you've shopped for white goods recently, but the options without wifi are relatively few, and mostly lower end models.
We needed a new stove, I wanted one without wifi/internet connectivity. Due to the above and supply chain issues that limited availability of a lot of models, I didn't have a choice and ended up with a model with wifi/internet connectivity. I have, of course, not connected it.
Buy used. A lot of the older models last a long time too, and only (rarely) need periodic wear parts replaced --- of which plenty are available aftermarket for cheap.
Supply chain issues aside, I don't think that's true. This is about Miele, none of which are lower end, and here's the first dishwasher I randomly looked at on their site, and it has no Wifi. https://www.mieleusa.com/e/built-under-dishwasher-g-7106-scu...
You still have to specifically choose a Wifi one. (Though again, I can see if availability issues might throw a wrench into that if you needed one right away.)
Sadly, I don't think dishwashers will last 20 years any more. Since 2005, I'm on my third dishwasher. The first one lasted 9 years, the second one around 5 (with one under warranty repair).
At some point the repairs/parts cost more than what the original dishwasher is worth.
Regarding the algorithm, I'm not sure they make a huge difference anyways. FWIW, The Technology Connections channel on YouTube has a couple of pretty interesting videos on how dishwashers work and how to get the most out of them:
