We will move to a system where we only ask 'can this question be answered by the scientific method?' If we use the scientific method to answer these questions we will uncover secrets of the universe that would never survive in the current system humans have designed.
The best scientists do not design their experiments with a goal of publishing in top tier journals. And as a community, we should not be encouraging this behavior.
The best scientists investigate questions out of pure curiosity and as a side effect publish the most impactful research.
Young talented people are already tackling really hard and high risk problems. If this is truly what young scientists want to do, they will find a way. 10 years of guaranteed salary is not the solution, but giving everyone the opportunity to be a scientist may be.
