One theory: the black death resulted in younger property owners, who
could
foresee a long life ahead, and weren't inclined to be staid and
conservative.
So, they innovated.

Younger property owners had no more expectation of a long life
during the plague years than those they inherited the property from.

A more likely theory: loss of work force allowed/required
innovation. You needed more efficient technologies, you couldn't
just
add more manpower. And, there were fewer "old hands" to say that's
not how we've done it."

On a side note, the Roman Empire had the technology to make steam
engines. But there was no demand, in large part because those who
could afford the expense of the machines, saw no need. They could
always buy more manpower.

"With Age comes Wisdom. Although far too often, Age travels alone."

It's claimed that Anthemius, the architect of Hagia Sophia in
Istanbul, did build an steam-powered device of some sort, possibly an
unbalanced engine.

Although Savery's engine of 1698 used steam under pressure, the
problem of making a strong boiler wasn't solved for another hundred
years.
