He's not pouring the coffee down the drain. He was demonstrating that adding cold water to the top forced the grounds to the bottom.

I have a toaster that is smart enough to perfectly toast any bread you can fit into it, regardless of density, thickness or even if it's frozen, and it's from the 1950s.

Yes, that one.

I guess he served the coffe first, but it sure looked like he poured it all away lolol 😂.

We're still talking about marginal, unnecessary things, but with a "smart" coffee pot, you could in theory start the pot when you're a few minutes away from home, if you like some after work. A pot connected to something like home assistant (which I have no idea if it exists) can brew the pot only on your workdays, or you can start it after you leave the bedroom, regardless of time. You could probably do quite a few "neat" things.

Yes. It is a guess. I'm using TVs and kitchen appliances as a basis for that guess.

Which, shame on me, I should go look for data on this. Someone has to have some statistics on it.

Hey you're not alone. I, too, was lost in the sauce and confused.
