How difficult is it for a single person to look up ways for cooking food?
I'm single, and I learned this on my own as a kid through simple observation of adults.
Sheesh... with the access people have to the Internet, you have a wealth of information at your fingertips to help you in this process.
As for 3d printing food - good idea actually, but only if the synthetic food in question is designed to be actually HEALTHY for the body and can even augment natural functions (such as boost production of youthful stem-cells and enhance the immune system).
We certainly have the technology and knowledge to do so, but the problem is, given the system we live in, they will probably just make it to be as 'cheap as possible' (monetarily speaking) and end up producing things of questionable quality that are no better, if not worse than GMO foods filled with pesticides and chemicals, which after a prolonged period of time likely produce a cumulative effect in the body and end up causing problems just so you would go to the doctor and be treated.
But, I digress, perhaps it will be different. Only time will tell.
