What technologies can be called the current black technology?

Black technology refers to science and technology beyond the scope of human science and technology or knowledge, lacking the current scientific basis, and even violating the known natural principles. Black technology is not based on the realized scientific theory, but in the name of science and technology, it uses the same things as magic, such as crossing wormholes, such as warp drive.

The actual situation is that we often say that a product has applied a certain black technology. This concept of black technology in reality is more like an "unexpected" technology application than an "impossible" technology. I think it is more practical to explain black technology in this way, otherwise it will be science fiction again. Then, let's continue to talk about products that are "unexpected" in those fields and are amazing enough to be considered as black technology.

In fact, a few years ago, it was a great thing to click faster without using a mouse. This function first appeared on public products, and many people were pleasantly surprised. Personally, I feel that alien products are mass-produced on earth. Recently Einstein said that the quantum communication satellite launched a few days ago was a ghost. It should only exist in legends, but it is actually created. It is impossible for black technology. Of course, because it is in China, the sense of black technology is particularly strong, and I even want to lick myself and verify whether I am dreaming.

The above example is even an example. Because the spotlight came and entered our field of vision. In fact, new changes are taking place in areas that we can't see every day. Every new change is unprecedented. As long as it is unprecedented black technology, there is black technology in every field.

In fact, whether technology is black or not is more a feeling caused by psychological factors. Before a black technology comes, it will be blown for several years. Don't we feel so dark when we really come?
