Yes, and I think having Taylor and Chowaniec on the board somewhat minimizes that risk; whether they can convince the others that this thing could spin cash out for decades is another matter. Don't forget that there is a lot more R&D to be done and presumably, a lot more cash to come from it.
Certainly these big numbers are not an immediate concern, there is a long way to go, but if the foundation is laid properly, a big building could be put on it.
