Replicator, for two reasons. One, post-scarcity overnight. Two, replicators are a combination of several technologies that would each be very beneficial to us. It’s like getting a dozen gifts in one. The only problem is that some jerk would use it to make a nuke and then use the teleporter part of the replicator to send it to a world capital. So… hoverboards.
@phendrick@rprebel Long ago in one of the Star Trek tech manuals (or equivalent background info, maybe from the Fasa Star Trek game) they covered a lot of speculative info. The computers that run replicators and designs they allow are tightly restricted and regulated.
Wouldn’t stop the crooks of course, and presumably would be used as justification for yet another massive bureaucracy tracking everyone’s machines and everything they made.
Creating a copyrighted object (or a specific pattern created by someone) isn’t free because a payment has to be made to the rights holder. That would include food; specific recipes and ‘presentations’ for food, though generic food and a ton of other ‘generic’ items wouldn’t have that component.
Still, would be cool, especially with an unregistered unit
There are a couple different designs that use magnetic levitation. One works exactly like a maglev train, which means the maglev boards follow a hugely expensive maglev track hidden under the pavement. If Lexus can make it work, it will be essentially an amusement park ride.
The other magnetic levitation technique works over a thick aluminum or copper floor. These can glide above the floor, but there is very little control over direction. Tony Hawk lost control when he tried it. These are possible today because we have some very high energy density batteries. It takes a lot of electricity to induce eddy currents in thick pieces of aluminum that create enough of a repulsive magnetic field to support a person. A few thousand dollars worth of batteries can keep a person hovering for minutes at a time.
I started to pick robot butler… but real hover board was lookin’ pretty good. Then I remembered all the Twilight Zone and Outer Limits episodes where the robot butler/maid started to take over and killed off the owners so… hover board.
I’m perfectly happy living without UFOs. I’m far too much of a hedonist to want food pills. I would end up a statistic in a gritty alien bar. And I would break my fool neck just looking at a hoverboard.
And yeah, I’ve read With Folded Hands. But I figure I probably won’t live long enough for the technology to get that far.
If the food pills were as good or better than an ideal diet, then, food pills. That implies a mastery of nutritional science and related biology. Food is horrible. It’s no good, expensive, time-wasting and I’m probably deficient in something in spite of the plastic-wrapped plants that I force myself to eat. And any effort I make to eat better probably is causing something to be hunted/fished/starved to extinction.
