Yes, any idiot -- even Dilbert's CEO -- can have a "vision." "Build me a flying car!" "Build me a spaceship that will go to Mars and back safely." And so on.
And it certainly takes money and a degree of power for large projects.
But let's have a moment of silence in salute to the ENGINEERS, the Dilberts and Alices, the unsung heroes who actually did all the "fiddly bits" left over after the "visionaries" were finished and who turned those visions into reality. The next time you whip out that smartphone, think about all the work that went into converting that idea from science fiction into reality and who did that work.
