Public enthusiasm for new advances is a key ingredient in influencing policy-makers to stimulate follow-up work with suitable funding, and it can be achieved far faster now that interested non-specialists can explore new research autonomously and can also be appealed to directly by scientists.

Accept the difficulty of what you cannot yet change. But do not accept the impossibility of ever changing it.
