A cook for you and your family doesn't exist yet, but technologists are working on it. Many appliance companies as well as gadget-startups are hotly & heavily working on devices that can prepare meals and shop for groceries.
A bot will keep you well-stocked. Amazon's ready to sell you its "Dash" button, ( $4.99 per button) that could replenish things like Ziploc bags and pretzel goldfish.
Samsung's Family Hub Refrigerator, ($3,499),makes shopping easier, and with LG, (electronic company working with Amazon Alexa) offers you recipes.
For $99 you can get a wireless SmarterFridgeCam that lets you see the contents of your fridge -- with its app tracks expiration dates on what you have, and makes recipe suggestions.
Bots can help you cook. The June Intelligent Oven ($1,495, called the Tesla of ovens) uses A.I. (Artificial Intelligence) to determine how long things should cook; with its ability to identify foods such as chicken, bacon, salmon, waffles, chocolate chip cookies; with its cameras, sensors, and temperature gauge it can even remind you when to flip what's cooking.
A smart baking scale can tell you how much sugar, flour, seasoning, you need to add, such as Drop ($79.95) or Perfect Bake ($72), which also can, with its app, help you substitute ingredients for what you don't have.
Various companies, such as Amazon Echo ($179.99) and Google Home ($129.00) sets a timer for you and reads recipes aloud from Allrecipes and Food Network.
Bots can keep you healthy.
HAPIfork ($79) helps you lose weight by preventing you from eating too fast or too much -- it vibrates and lights up to indicate this.
SmartPlate Top View ($79) works with a scale and app that helps diners portion their meals and maintain a well-balanced diet.
Pryme Vessyl ($99), a smart cup, can prevent dehydration, track daily water consumption with its meter that lights up to indicate your hydration level throughout the day; it integrates with Apple's Health App for the iPhone, so you can plug in your water-metics along with other fitness-metrics.
....well, I love to cook. I don't use recipes. I know how to use all my appliances efficiently. I have a timer on the stove that I rarely use. I keep a shopping list (with pencil attached) stuck to the fridge and keep it up-to-date. I shop for food online, and have it delivered once or twice a week. As for hydration, well-balanced diet, eating too fast, expiration dates ... Golly, good heavens....
A bot in your kitchen would be like having your Mom, or a stickler Mother-in-law looking over your shoulder!!!!
