It'll end up like the shuttle:
1) Start with a design and set of specifications, a delivery date, and a projected cost.
2) Congress will cut the budget every year.
3) The scientist and engineers will adapt by changing the design to meet the budget. But the design will be in constant change because the budget will be in constant decline.
4) In the end, the system will not meet the original design purpose, nor specifications, will not be ready by the intended date, and will exceed the original projected cost because the design was in constant redesign chasing an inadequate yearly budget.
5) Capable or innovative personnel will become frustrated and leave, and the project staff will change until it's largely bureaucratic because they aren't bothered by a lack of progress.
