Technology has generously given so much we enjoy in the world around us. The computer (or smartphone) you are using right now, for example, has connected you to List25 in a way that would not have been possible if not for the technological advancements of our hi-tech era.
The good news is that technology won’t stop anytime soon, giving us new things that we can use for a good purpose. The bad news, however, is that certain technologies should be available by now but they are not.
The following list of 20 Technologies We Were Promised That Should Exist By Now is clear proof that we have not come as far as we wished we had.

The idea of flying cars is not new. Actually, the first man mentioning them was Henry Ford, back in 1926. He even created an experimental single-seat airplane that he called the “sky flivver.” The project never took off.
The next attempt was conducted by the Soviets in 1942. They tried to allow a tank to glide onto a battlefield after being towed aloft by an airplane, to support airborne forces or partisans. A prototype was built and tested, but the whole idea didn’t get off the ground (no pun intended).
Automaker PAL-V recently exhibited a demo car that costs around $621K. This car is supposed to fly but, well … have you seen any flying cars lately? We sure haven’t.
Fans of Star Trek probably understand the idea of teleportation. Science lovers are also familiar with “quantum teleportation,” the theoretical technology of instantly transmitting information from one location to another.
Researchers once claimed that we would be able to do the same with humans but, as you can see for yourselves, this still happens only in Star Trek movies.
Despite what popular science articles may tell you, this kind of Trekkie teleportation is not likely to happen any time in the foreseeable future, simply because our technology cannot transmit human atoms from one place to another.
The Dyson Sphere
Proponents of solar power know that only a tiny fraction of the sun’s total energy strikes the Earth. What if we could collect all of the sun’s energy, though? If that were possible, we would be able to use some form of Dyson sphere, sometimes referred to as a Dyson shell.
Physicist and astronomer Freeman J. Dyson first explored this idea as a thought experiment in 1960. Dyson imagined a solar-system-sized collection system of solar power. He pictured it not as a power source for us earthlings, but as a technology that other advanced civilizations in our galaxy would, inevitably, use.
Dyson proposed that searching for evidence of the existence of such structures might lead to the discovery of advanced civilizations elsewhere in the galaxy. Sixty years later, however, this remains a theory.
The concept of time travel has always captured the imagination of physicists and laypersons alike. Normally, it should be number one on our list.
However, the fact that time travel has even been discussed as a “realistic” possibility of the “near future” (and failed each time) makes the whole subject comical.
So, the question remains: Is time traveling possible? Of course! We’re doing it right now, aren’t we? We are traveling into the future … one second at a time.
