The fact is that there are numerous people out there with popular YouTube channels that allow them to pursue an income. I, myself, have considered creating a channel themed around a couple different topics (and not likely what many, here, would suspect). I would not expect it to really replace an income, and think it would become a detriment for such projects if they were able to do so. People quickly realize that videos draw large amounts of money when they are first published, then taper off in popularity afterward. I notice this trend in my fan-fiction, so it's only natural that those who get more than ego strokes from video views take note of it, as well. It pushes people to release videos more frequently and to descend into 'let's play' or other meaningless types of nonsense video posts that cheapen the channel.
Which is why the channel, itself, would be built in conjunction with a business and products. What kind of products? Somewhat classified, however, imagine being able to 3d print almost any element and even form exotic ionic/covalent bonds with other elements before depositing those atoms with a specified energy onto/into a solid matrix with sub-micrometer accuracy. In theory, organic molecules could be deposited this way, too, but the process would require hard vacuum, and that would ultimately create a number of limitations on what materials could ultimately be processed.
Of course, something that can have wildly varying material composition would need a bit more than just your average solid model and would, itself, need quite the software suite backing it up. The easy part is the actual mechanism, which is effectively on par with what kinds of stuff is currently being hammered out within restricted access programs, I would imagine. The harder part is the software interface.
However, it means that electronics could be directly embedded within a metal impregnated ceramic matrix consisting of a very accurate micro or nano structure of composite materials. In other words - it means meta-materials not just as a piece or a part, but as an overall design philosophy and looking at every piece of an assembly contributing to more than its structural function. Struts become batteries, capacitors, conductors, or even signal processors with antenna arrays. Some piezoelectric effects could potentially be exploited for micro-actuators, temperature control systems, or even structural reinforcement that has barely been theorized as possible, yet.
I should have begun all of this earlier, and have experienced a number of setbacks - many out of my control, some choices I made on moral grounds (a great many people will be absolutely astonished at what I have sacrificed and why), and quite a bit because of my own care-free/lazy disposition. However, it has also given me quite the opportunity to learn a bit more of other things within the world before I start off down my own road.
By the time I have my equipment in a state in which it is ready to sell, I almost will not need money - interestingly enough. Of course, I am also not stupid. The project's details will be TS:SCI and handled appropriately on sufficiently isolated systems. There will be an insurance policy in the event I am killed, but it's better if everyone thinks I am simply an egotistical narcissist who is all talk and no hat, let alone cattle in the first place.
Anyway, I have deviated from the topic, considerably. Why am I even talking? Balking. Squall-king. King sing bing ring. Alas, I have still never figured out whether it is a foxy box, or a boxy fox.
