This is often a good thing, as it can add some valuable functionality, but it drives me nuts when it goes wrong. I've had to deal with washing machines where the mechanical bits were perfectly fine, but the electronics fried. That can be expensive to fix, to the point that throwing it out and buying a used one off Craigslist is the more economical option. Same with modern stoves. I have never in my life gotten any benefit from fancy electronics on a washing machine, and the only sensible reason for non-mechanical parts on a gas stove is a timer, but I'd honestly prefer a simple pure-mechanical one that is going to last forever.
