Over time, there have been several speed improvement for several 
features. For example, focal blur, on the exact same computer, is 
significaly faster now than using version 3.6.

POV-Ray also got faster for some other features over time. Also, the 
hardware performance increased exponentialy.

BUT... We still have scenes that take just as long to render as they did 
in 1980.

As computer's power increased, and new features are introduced and 
improved, artists made more complex and demanding scenes, and also 
rendered at larger resolution and beter antialiasing settings.

The use of advanced features, once rarely used, became common place. In 
the 90's, radiosity and area_light where seldom used.

We commonly use media to make clouds while there was a time where all 
clouds where made using sky_sphere and, some times, planes using mostly 
transparent pigments.

Give peoples super computer 1000 times faster than today's computers, 
and they will make scenes that will take the same time to render, and 
even more, as they demand at least 1000 more computation.
