It invariably produces a concoction (which most people found unpleasant) that is "almost, but not quite, entirely unlike tea".

Jacob_Roberson: Citation needed. I think they're less susceptible than any mammal.

Too lazy to dig it up, article on NPR yesterday

I hope I'm dead before we all have to change our perspective about what we think of as food. I don't want to eat 3D-printed insect protein squares.

"So we eventually have to change our perception of what we see as food."

Jacob_Roberson: So I see a system that will help with space travel if it works (they haven't tried building it yet). But then they talk about feeding more people than we can today and it becomes entirely science fiction - you don't get more efficient output by increasing the amount of energy input. And they don't seem to understand that's a problem they'll never get around since they're using a gadget instead of just grabbing some things and cooking them like a normal person.

We might very well reach a point where the "gadget", powered by a field full of cheap photovoltaics, produces more than the same field covered with grass and cows. Heck, given the relatively low efficiency of photosynthesis, it might outproduce a field full of human-edible grains or fruits.

Of course, efficiency isn't everything.

Nem Wan: Feeding the crew could be done in a manner conceptually similar to the proven method of fueling the spacecraft:  staging.  Just as the spacecraft begins with multiple stages and returns with just a capsule, cannibalism would reduce the crew to a minimum compliment over the course of the mission.

Modest. I like it.

Jacob_Roberson: Quantum Apostrophe's head asplode.

Careful.  I got a timeout for making a similar comment about QA and his aversion to utopian 3-D printing, for "calling out another Farker".

It was not malicious, either - pretty much the same tone as your post.

Stone Meadow: 2) farming them in quantities sufficient to feed the human population will not involve the same environmental issues as farming vertebrates?

Actually yes bugs are more efficient at the feed input -> meat output game. we'll take longer to get the same environmental issues.

We're still printing matter with matter.

None of this matters until we're printing matter with energy.
