I agree entirely with the sentiment, but there is a massive psychological difference between virtual problems and real ones.
With virtual problems, the rules are known and consistent, and the only potential barrier to success is the limitations of the user's abilities. If the user can accurately assess their own skill level, they can know if the problem is solvable, and possibly the time frame in which this can be done.
Big, real problems are awash in variables far beyond the control of any one person. They may not be solvable given current restraints. Many of the "best" governments in the world, led by the most educated and intelligent people, and backed with enormous budgets are undercut by the chaos of global economics, damaged by misinformation and false intelligence, aggravated by the stupidity of other actors, and in turn conduct their own activities that damage the prospects of peace, or health and security for all.
I might commit my life to a cure for cancer or world peace, and thus squander the next 60 years away because the world, as a majority, is not ready for those things. The Sudoku puzzle, on the other hand, I can solve before I finish breakfast.
