4. Camera-wearing freaks: fulltime vloggers like Justin.tv and bloggers who video-interview everyone at conferences (very annoying). Think about it: the chance of anything stupid you do ending up on YouTube is increasing exponentially alongside camera-equipped mobile phone shipments.... scary.
3. Agressive in-car GPS: (or worse: GPS on your phone) those annoying voices will multiply, telling you where to go. The proliferation of instructions will particularly annoy girlwithoutawatch, who hates being told what to do by me, much less by a gadget.
7. Energy-saving wonks: those people who convince you that you can save the planet by turning off your new Intel-Mac at night but still drive a Porsche Cayenne by day. Hmmm.
I would add a few annoying future technologies of my own:
8. Fugitive avatars: surely it's just a matter of time before IBM or Toyota's digital spokespeople from Second Life cross over into the Web or onto our TV screens to plug their products. Do we all have to become cartoons to interact in future? (The picture on the left is IBM CEO Sam Palmisano's avatar at an IBM 'townhall' meeting with his virtual employees.... really.)
9. Voice-activated devices: is it just me who prays that voice activation will not become ubiquitous, as everyone seems to predict? It's bad enough that people walk down the street talking into their earpiece wires. How annoying will it be when your neighbor in the subway shouts into his phone "Oven: preheat to 200 degrees!"?
10. Intrusive car safety features: this is more of a current technology gripe if you drive a BMW 7 Series, but for the rest of us it's a future problem: lane departure warnings, blind spot detection, parallel parking assistants, what next? You had me plenty annoyed at those bing-bing-bing seatbelt reminders!
11. Ubiquitous RFID tags: each year that passes without the RFID adoption predictions coming true is a relief. Who likes the idea of RIFD tags in our clothes which may or may not have been de-activated at checkout? I've got enough paranoia with Ken Livingstone watching (and taxing) my every move, I don't really need Austin Reed to know where I dryclean.
12. More inane communication methods: Email, SMS, MMS, IM, chat, blog, Twitter... I'm sure there are some tiny fragments of our time that have not yet been exploited for communications. What do I do between my last Twitter and my next blog note? Surely I need to let my social network know what I'm up to?
