AI tech indeed had put power into the hands of common Humanity, to create and even profit from such efforts made by many, so many, in the tech industry.....
1. However, do know that AI tech DO have its limitations.
It takes very very much effort thru trial and error to produce something virtual that another would like, or even pay for it. The competition is STIFF, as there will be BILLIONS of Humans whom will want to try this method to bring their thoughts & some with even devious means to profit from others, in either cash or in kind... Thus, be careful...
2. One MUST have the CREATIVITY to produce a movie, with very much knowledge on camera techniques, sound, lightings, environments, choice of actors, actresses, STORY LINE, that would appeal. It's like writing a book. Anyone can put a few sentences together, but it takes one to fully understands what another wants that would appeal.
There is much more, but my point is that it is not as easy as it seems, even with AI, because if one does not know the steps, the costs, the creative efforts, one may only had wasted one's time and effort, just like writing a book.
For example, if one just input a prompt - a man walking out of an office- the AI movie maker will give you a 5 sec clip of some man in an office attire stepping out of a door, as you had not SPECIFY - what kind of man, what kind of building, what kind of attire you wanted the actor to have, is the actor black or white, what time of day, etc, etc, resulting you would have to SPECIFY again, time and time again to get it right.
Thus it is not easy as one assumes it to be.
3. In the end, there is a market for profitability, but only if one has the creative mind, taught and tested, as well as the biz acumen to make some money out of one's efforts, either by oneself, or by a enterprising organizer - the manager whom will earn the standard rate of 80% of your efforts to organize, plan, market, other members of like minded team members for collaboration, etc, etc, and the creative person be easily exploited.
4. Equally, as tech had placed POWER into the hands of Humanity, such POWER comes with RESPONSIBILITY to others. thus use it carefully, for good and not misuse it for bad that would destroy innocents and Humankind......
