There are definitely some uses for a washer and drier with "smart" capabilities. Just alerting me when the program is done so I can put the next load is great. The cycles are not "fixed time" anymore, they all weigh the load and end up variable.

I could do without them, and it's not the end of the world if the laundry stayed 20m or 1h longer in the drum. It's practical, and hopefully not a critical feature of the internal board. One could argue if alerting is really a "smart" feature either.
