I think it means a lot of people are going to lose a lot more money than $1 Ether would have meant. 1. The halting problem states you can't predict what a turing complete program will do, until you run it. This means to some degree, that you can't predict what your "smart" contract will do, until it does it. Thus turing completeness causes security to be far, far harder than non turing completeness. This is how you l…
The "Halting Problem" is a red herring here - eth transactions are technically not Turing complete since they automatically halt when they run out of the finite supply of ether attached to the transaction. Saying that ethereum isn't feasible because of the halting problem is like saying cars aren't feasible because an object in motion stays in motion - there are countless practical ways to manage it, and if nothing else stops you, in the end you'll definitely run out of gas.
