Well to be cynical - if most people are blithering idiots and most people don't amount to much, it could be true that most smart people don't amount to much and most people in charge are idiots while still true that being smart makes you much more likely to be in charge :o)
I wonder if there's a way you could help this with software. I remember reading a long time ago about singing pitch training by realtime headphone feedback (like - if you're singing flat, you are feed back your voice distorted even more flat[1]). I wonder if you could detect and exaggerate differences in prononciation.
you could have a ring of people, with their own loyalty cards, use them for a bit, rotate around, offset any loyalty points differences with a bitcoin transfer.
By implanting a small magnet normally in a finger, moving your finger through an electric field causes small movement of the magnet, so you can 'feel' electric fields.

Wouldn't it be pretty toxic (especially if it's a vapour?) In a sealed component in a datacentre that problem doesn't matter, but they're speculating about home use also.
Yes, there's an interesting thing on that here:

I haven't looked at enough philosophy to be able to figure out what I'd place myself as, average-utilarianism also seems to lead to morally-counter-intuitive stuff.
That's essentially average-utilitarian (has the happiness of a random person in the population gone up?); I guess many people are closer to total-utilitarian (ie. the total number of happy/surviving people is also important).
Relabelling is the marketing game; to get your businessy-idea-book in the best-sellers list you need everyone to replace "practice makes perfect" with "10000 hours".
