The difference between getting competent with Postgresql versus MySQL was just a few hours. In the scale of a project such a difference dissolves into complete irrelevance, yet it was enough to sway many to use MySQL when it was severely deficient comparatively (though with its adoption it saw love that brought it up to if not beyond parity).

The same is true with many technologies and approaches. Projects that consume thousands or tens of thousands of hours, with a toolset chosen because it represented an outset savings of single-digit hours.

Changing in the future is seldom as easy as it seems in those early days.
