I agree with almost all of this save the part about the gender balance eventually evening out.

I don't know that there ever will be parity and I don't know that that is a problem.

Proportional representation is not always desirable or natural. Different groups do things in different proportions. Such is true of men and women; in aggregate, they do things in different amounts. This is not de facto evidence of insidious discrimination; we don't seem to assume so in the case of men not being in female-dominated industries like education.

Ultimately the lack of proportional representation is mostly the result of real differences between men and women. To try to create proportional representation would either demand hiring tokens or heavy duty social engineering to reduce gender differences. I don't like either option.
