Ultimately it means you'll be able to find a recipe online, have the ingredient list and preparation instructions sent to your mobile device, and your smart oven will be automatically configured with the correct settings.
I fail to see where any of this is saving me much time or effort compared to what I can do today. We already keep our grocery list in a Dropbox file. One might argue that knowing you're out of something is an advantage; but in practice it's too late at that point - and "running low" is dependent on what you're planning to eat over the next several days.
Having a recipe displayed on my phone or iPad is certainly handy - but I can do that now, with no more effort than is described above ("find a recipe" is the only effort involved - and you have to do that either way).
Configuring the correct settings on my smart oven? That's like 5 seconds - tops - on my current oven. And my current oven is at least 25 years old! I have to turn a dial to set the temperature... oh, the humanity!
Seriously, as far as I can tell the only "advantage" this particular corner of the Internet of Things offers is either to 1) advertisers hoping to sell me stuff; or 2) other various parasites.
