Maybe in the future...
In all honesty, i wish i evolved far enough to synthesize everything i need on my own.
Instead of a mouth and digestive system, i would like to have a desintegrator from which the beam i could aim at something and consume it by taking the atoms apart and taking them in with some kind of tractor beam.
Internally i could just create what i need and the sensation of food could be mimicked by internal taste emulation when desired.
As long as the elements i need are in the object to consume, i would be happy.
Would be great when living among the stars.
