Let me start with the caveat that I'm in my early-mid 30's and progressing ahead of time into the cranky old man stage stage of life. In general though I find this style of automation has too many exceptions and the negatives of those exceptions generally outweighs the benefits.

To take the coffee pot as an example. I'll hit the snooze button between zero and 10 times a morning, so automating the coffee machine would often result in cold coffee. Other times, if I've get a bit to drunk the night before, I'll skip the coffee, so the automation would be a waste. There's also some introduced mental overhead of having 2 workflows for the same thing, if I want a coffee, I go make a coffee, but now I'd have to think about if this was one of the automatic ones or if it requires manual intervention.

I may be atypical in this, but I have largely automated the process myself. I wake up and while I'm still on autopilot fill and turn on the jug (we don't do coffee pots here) go pee, come back and put the instant coffee in and the jug is boiled by then. There simply isn't room to optimize much further than that. I'm also a bit of a stickler for fresh water (incident with a cockaroach ~25 years ago), so I don't like the idea of filling the water the night before. If I wanted too though, I could automate turning the jug on in the morning with an electrical timer 30 years ago.

I think I could come up with a similar list of issues for all/most of your other examples considering most of them are more complicated, particularly the fridge one.
