The virtual reality that we have been shown in science fiction films for years is closer than it seems.
Pictures are easily drawn with a click in DALL-E, Midjourney, Stable Diffusion and similar bots. And this is done literally in seconds.
Videos are not as perfect as we would like them to be, but Runway or, let’s say, Pika are making big strides forward.
Everything is clear with texts anyway.
The question of power remains. One thing is to throw out a dozen sentences, generate several pictures or a short video. But to do this on the scale of hundreds of thousands of devices simultaneously is a quite different thing.
Only quantum computers can cope with such a volume.
A quantum computer differs from a traditional one in that it does not work sequentially. To solve a problem, a classical processor with the architecture we are accustomed to first takes one step, then another.
A quantum one, due to superposition, seems to “look” at all options at once, processing them simultaneously.
Look here: you are trying to match a key to a door lock. In a normal situation you try them one by one: you take one — it doesn't fit. You take the next one. And so on until you find the right one.
Now imagine that you are holding the whole bunch of keys and simultaneously inserting them into the lock. The right one fits right away. This is roughly how a quantum computer works — it immediately covers all the options and gives the right one at the same time.
Yes, quantum computers already exist, but there is a nuance: they need a temperature of absolute zero to work. Under normal conditions, it is impossible to create ultra-low temperatures. And this is not the only problem — there are still a lot of technical nuances that have not been fully resolved. But, all this can be resolved.
Therefore, the metaverse is no longer the future, it is a matter of time. And it seems that there is very little time left.
