After 20 years as a vegetarian one told me she didn't think she'd be able to digest meat any more, but I think that was her own speculation and not from anything she'd read.
I didn't say I'd like it, but it could be mandatory when the population is 50 billion.
No, that's a lot of bull!!!!
MREs are way of our future, for population of 50B as noted below.
For food, important factors are 1:taste, 2:smell and 3:look. 3D foods are for look only. Why would it be mandatory to provide it for mass population. MREs would do just fine.
Yeah but this is steak we're talking about! Not buggy-whips or Betamax tapes!
I thought of that after I posted -- you could make a 3D printer that would scan the shape of a cake, then apply icing.
I hadn't thought about custom-printed cookies, but yes!
The hard part (IMHO) wouldn't be the electro-mechanical part -- it'd be food science coming up with recipes for the goo you're squeezing out of it so that it'd be tasty and printable.
