When the cartoon present The Jetsons debuted in 1962, it amazed the world with its imaginative and prescient of the world a century later — this was a way forward for flying vehicles, robotic housekeepers and sensible houses set within the ozone layer. Over 55 years later, we nonetheless don’t have any tube homes within the stratosphere, and our humanoids can barely stroll.

We’re 3D printing a variety of stuff, however there’ nonetheless no magic dinner-maker. And the tech wizardry that has materialized is definitely not inside attain of the typical govt at a sprocket firm. Right here’s a have a look at a number of the stuff that has made it to actuality, however isn’t commercially viable but.

Nanobots and humanoids

We’ve got humanoids that may stroll, speak, take orders. However none of them can do all three. Those that transfer can’t converse, those that talk can’t deal with stairs. We’re so far-off from the age of sassy housekeeper Rosie, the sardonic Tars or Jarvis — or certainly the Terminators — that we would as properly nonetheless be within the 1990s.

In the meantime, the humanoid bots that we do have are so costly, even firms can solely afford to lease them, as promotional gimmicks.

As for the nanobots that may be ingested and piloted via the human physique with precision, to kill tumors or repair organ injury — properly, we’ve to date solely made it to medical trials on rats.

It doesn’t assist that nanotechnology requires gold, silver and cobalt of virtually absolute purity.

Researchers consider we could have injectable nanobots by 2030. We’ve obtained Alexa and Echo et al, for now. Maybe it’s higher gradual than sorry. What we undoubtedly don’t need is Hal. “I’m afraid I can’t try this, Dave”.

Jetpacks

 On the opening of the 1984 Olympics in Los Angeles, 1000’s of spectators (and hundreds of thousands extra watching on TV) witnessed historical past being made as a person flew in utilizing a jetpack. Prototypes come out yearly, together with one created by JetPack Aviation this yr. However they’re loud and heavy… and don’t fly very far.

Hoverboards

A levitating skateboard would be especially helpful with potholes and waterlogging, wouldn’t it? In 2015, Lexus created a hoverboard with powerful magnets that cooled to -197 degrees Celsius, allowing the board to ride along a track hidden in the surface of the skate park. But it couldn’t float over regular roads. So we’re still waiting.

Interstellar travel, homes on another planet

Or at least the moon? They promised that by now we’d be looking at a view of Earth from thousands of miles away, at least. We’ve sent probes, landed rovers, gone beyond our solar system. But only a dozen people have actually touched down on another celestial body, and none has gone beyond the moon.

With the end of the Cold War, the space tech race eased and the focus shifted to communications and monitoring satellites. All the exciting stuff on other worlds is now being done by robots.
