This is crucial in the midst of loose and fast comparisons between technologies in the past and what we have now. Can a piece of complicated software like Bitcoin be re-engineered from the ground up? Yes, certainly, but that is a tough road to take, I would think, if you want to do what Bitcoin does at its core. Bitcoin, the software, solves basic problems very well and is thus the basis of many altcoins. I'll invest in the next big coin if it is significantly better than Bitcoin while continuing to maintain Bitcoin's core value argument.
