In future versions, can nrg and mass be interchangeable? For example, Bot 1 has 3000 nrg and 100 body. The code tells it to expand its body by exchanging nrg for more body. For a small 'transaction fee', a certain amount of nrg will be converted in body. Obviously, this exchange shouldnt be free but I think it would be a good idea and will be a puzzle for DNA programmers to think about: nrg or body?
