It seems to me, we don't need to refer to Lister and Kryten to experience the 'connected-up' toaster. It's been done already. At least, according to this meme (an oldie, apols if you've read it already, but doesn't seem to have been posted yet on this forum):
Once upon a time, in a kingdom not far from here, a king summoned two of his advisors for a test. He showed them both a shiny metal box
with two slots in the top, a control knob, and a lever. "What do you think this is?"
One advisor, an Electrical Engineer, answered first. "It is a toaster," he said. The king asked, "How would you design an embedded computer for it?" The advisor: "Using a four-bit microcontroller, I would write a simple program that reads the darkness knob and quantifies its position to one of 16 shades of darkness, from snow white to coal black. The program would use that darkness level as the index to a 16-element table of initial timer values. Then it would turn on the heating elements and start the timer with the initial value selected from the table. At the end of the time delay, it would turn off the heat and pop up the toast. Come back next week, and I'll show you a working prototype."
The second advisor, a software developer, immediately recognized the danger of such short-sighted thinking. He said, "Toasters don't just turn bread into toast, they are also used to warm frozen waffles. What you see before you is really a breakfast food cooker. As the subjects of your kingdom become more sophisticated, they will demand more capabilities. They will need a breakfast food cooker that can also cook sausage, fry bacon, and make scrambled eggs. A toaster that only makes toast will soon be obsolete. If we don't look to the future, we will have to completely redesign the toaster in just a few years."
"With this in mind, we can formulate a more intelligent solution to the problem. First, create a class of breakfast foods. Specialize this class into subclasses: grains, pork, and poultry. The specialization process should be repeated with grains divided into toast, muffins, pancakes, and waffles; pork divided into sausage, links, and bacon; and poultry divided into scrambled eggs, hard- boiled eggs, poached eggs, fried eggs, and various omelette classes."
"The ham and cheese omelette class is worth special attention because it must inherit characteristics from the pork, dairy, and poultry classes. Thus, we see that the problem cannot be properly solved without multiple inheritance. At run time, the program must create the proper object and send a message to the object that says, 'Cook yourself.' The semantics of this message depend, of course, on the kind of object, so they have a different meaning to a piece of toast than to scrambled eggs."
"Reviewing the process so far, we see that the analysis phase has revealed that the primary requirement is to cook any kind of breakfast food. In the design phase, we have discovered some derived requirements. Specifically, we need an object-oriented language with multiple inheritance. Of course, users don't want the eggs to get cold while the bacon is frying, so concurrent processing is required, too."
"We must not forget the user interface. The lever that lowers the food lacks versatility, and the darkness knob is confusing. Users won't buy the product unless it has a user-friendly, graphical interface. When the breakfast cooker is plugged in, users should see a cowboy boot on the screen. Users click on it, and the message 'Booting UNIX v.8.3' appears on the screen. (UNIX 8.3 should be out by the time the product gets to the market.) Users can pull down a menu and click on the foods they want to cook."
"Having made the wise decision of specifying the software first in the design phase, all that remains is to pick an adequate hardware platform for the implementation phase. An Intel Pentium with 48MB of memory, a 1.2GB hard disk, and a SVGA monitor should be sufficient. If you select a multitasking, object oriented language that supports multiple inheritance and has a built-in GUI, writing the program will be a snap. (Imagine the difficulty we would have had if we had foolishly allowed a hardware-first design strategy to lock us into a 4-bit microcontroller!)"
The king wisely had the software developer thrown in the moat, and they all lived happily ever after.
Yes I know it's dated! Unix and Pentium processor.....
(or lets be honest, a mid-senior management meeting outside of all but a few of the most tech focused companies). I doubt even the GCHQ rep really knew what he was talking about. The cock up before conspiracy part of me would assume this is one of those situations where someone comes up with a rather speculative idea (there's always a few people like this in most organisations in all three sectors, lots of ideas, quite good at the spiel, management likes them, practical implementations? not so much) and someone in senior management runs with it (cos it'll look good) it never really leaves some speculative analysis and a dodgy powerpoint presentation or two but that's fine because a few people have ticked some appraisal targets off and it looks good for career progression.
