Well... ok. Let's look at the black-lining of this happy puffy cloud.
1. Self-Driving Cars: Truckers and cabbies are all going to lose their job. It'll be a big wave of unemployment for a sector of the populace that was already wasn't doing well. A lot of disenfranchised people with not much to lose is a worry.
2. Clean Energy: (this ones harder... ok, got it). It's a step towards these clean-energy eco-nuts outlawing coal. You'll have to.... (No that doesn't make any sense... AH) The more people that switch to distributed power generation, the less support the power grid will have. It benefits from economy of scale, but chip away at that and have half the populous stop paying, and you have problems for a public utility. The first to go with be mandates for rural electrification. Farmers will be cut off. Without the power lines being subsidized, communication lines won't be able to piggyback. (It's a stretch, but it's something)
3. Virtual and Augmented Reality: You know how kids these days barely look up from their phones? Get ready to have blind-deaf (sadly not mute) meatbags ignoring you with twice the power. Kids wandering into streets chasing their pokemon. If they can overlay their own better reality, they'll disconnect from your reality. Oh, and this.
4. Drones and Flying Cars: With a camera on there, now it's feasible and cost effective to operate a panopticon where the FBI or anyone else with $200 are always watching.
Flying cars are one of those classic tropes for letdowns. In reality, it's just more expensive to operate a plane. I know a pilot with a shitty commute and there's an airstrip RIGHT next to work, but he still drives simply because he can't justify the cost of a plane. Automate the pilot license requirement, and rich people probably will fly everywhere. Let's hope the budget for road maintenance is still approved.
5. Artificial Intelligence: Remember those truckers? Get ready for whole swaths of office workers to go away. It's not like everyone from HR will get laid off. But none of them will touch paychecks and there will just be two to handle sensitivity training. Generalist doctors, the sort that diagnose you when something is wrong, could probably be replaced by Watson right now. The only barrier is who do you sue when it screws up.
6. Pocket Supercomputers for Everyone: Uhh... something something, company leash you can't run away from, tracking you everywhere, the crushing disappointment that we gave everyone super-computers with the grand sum of human knowledge at their finger tips and the ability to instantly communicate with anyone anywhere (and have the language translated for you) and they only use it to look at pictures of cats.
7. Cryptocurrencies and Blockchains: Yay, a secret money to buy cocaine online with! And as for business-minded uses of blockchain technology... I'm still not sure how that's any different than running a co-opt.
8. High-Quality Online Education: It's been there for a couple decades and people are still pretty stupid and uneducated.
9. Better Food through Science: (This one is also hard)
10. Computerized Medicine: Robo surgeons are going to get hacked and then they're going to hack you.
11. A New Space Age: (I could probably find something negative about this, but I really like space. SPAAAAAAAACE!)
Ok, I ran out of steam at the end. Too much pessimism is as bad as too much optimism.
