Jim is a man of the 2050’s. A busy man, keen to stay fit. His electronic assistant Pat is a tiny computer that Jim carries with him. Jim’s words are black, Pat’s are blue.
Jim can spend his entire day focussed on work – which will be the subject of a separate post. Pat only interrupts when Jim has spare time at breakfast or when walking. Pat talks to Jim normally, via an earpiece. Jim talks to Pat normally if alone, or via his wrist watch if in company, which has a touch screen for simple answers. So – what about after work?
The ingredients come precisely packaged in the correct amounts and to the highest quality and freshness. The delivery methods will be the subject of a later post. Pat does not duplicate anything that Jim already has. Amounts are calculated to meet personal needs. There is no waste in the ordering process.
During the cooking of the meal Pat helps Jim by scheduling everything. Jim can focus on the cooking. Complex food is expected in 2050, with several small courses. Pat looks out for problems, and reminds Jim when things need doing so that everything will be ready for his guests. There is no food spoiled during cooking.
The close of day report from Pat covers input of all major nutrients. It compares those with recommended inputs for Jim’s age and weight, for his exercise level, and for his sporting aims. It draws his attention to any unusual readings, for example if recovery time after exercise is too long.
I chose Jim for this first example because, as a single man, his out of work life is relatively simple. A later example will deal with how e-assistants can help women and families, where they will cope with greater complexity and provide much greater benefits.
The key things that make Pat effective are:
Pat handles all purchases, so he knows what food comes into Jim’s house. He knows the content of processed foods because he gets that from the seller. He pays for all restaurant meals and snacks and drinks.
Pat can see, because there are cameras built into Jim’s glasses. However he can do more than see – he can understand what is going on. Pat recognises plates by their shape, he can read the labels on packets, he understands the colour and texture of different foods. Pat’s vision is stereoscopic so he can also estimate the shape and size of a pile of food on Jim’s plate, and by looking again at the end of a meal he can estimate how much Jim has eaten. The information stored at breakfast includes a list of everything that Jim has eaten. It also includes the amount of food left in cupboards and fridges, so Pat knows when to re-order. If Pat isn’t clear on some point, he will ask. For example he might not see how much cereal is left.
While Pat acquires images, he does not store them. He extracts the basic information he needs, then discards them. This is considered polite.
Pat can hear and analyse speech in any language, but again it is polite to only store certain types of information such as dates, times, and promises. E-assistants communicate their recording status and ensure they are ‘polite’. Pat will tell Jim if his friends are recording what goes on over dinner.
Pat knows how much exercise Jim takes by looking at movements and Jim’s speed.
Pat can sense various body functions such as breathing, pulse, and brain activity. He knows when Jim is happy.
Jim has agreed that he can share personal data with the e-assistants of his friends, including Kat and Al. So Pat can say exactly what food will suit everyone’s tastes.
Pat scours the internet for local bargains or well regarded local businesses. In 2050 the amount of such marketing information is beyond the capacity of humans to adsorb. Pat handles all order placement and payments, with no involvement from Jim except to approve the more important things that Pat proposes to buy.
And how does all that stop food waste? Because Jim buys no more than he will eat, and only eats what his body needs. The load he places on planetary resources is far less than an average 2013 western man. See the related articles below for different views of how much we waste by eating too much red meat. See also the background page link at the end of this post.
Why can’t we do this now? Firstly because the technology is too bulky, and image analysis is too slow and unreliable. Those things will change and this technology will slowly become more convenient and reliable.
Secondly it takes time to build the required conventions. Restaurants and food sellers will need to provide information in an agreed format. That will take time. Likewise it will take time to develop a ‘polite’ mode so that cameras can be worn to dinner.
