Technology will eventually be the downfall to humankind.
It would annoy me to come home to a digital environment especially if I had just left an office surrounded by computers.
All we really need is a telephone, television/hi-fi and PC.
We don't need mirrors that tell us what to wear or what our friends are wearing. We don't need digital wallpapers. We don't need holograms of artefacts or an in-house bus timetable.
We rely on technology so much that I fear we're becoming more and more stupid by the generation. How many of you can memorize 5 numbers from your phonebook? When was the last time you did long division? If computers start dictating silly little things such as what recipes to use, we won't need to use our brains at all!
They're clever ideas, but at the same time ridiculous and hopefully none of them actually make it into production.
Pretty much all of the gadgets rely on lighting and it would be awful having to live in the dark just to be able to use all those ideas.
And I'd hate to imagine how much power consumption that requires as well...
