Stronger and faster-depends on how "strong" and "fast" are defined.

Even if you are defining strong as weightlifting or fast as running a race, we still find that many women are stronger and faster than many men.

In any case, in our society weightlifting and physical lifting objects are not as useful as they once were and so if most men are able to lift more weight than most women it is simply not as important as it once was; same with running fast.

However we have chosen to become a machine society and about strength and speed have new meanings.

Actually this is a benefit to men ho were physically strong and speedy in running. The increase utilization of thinking and employment and deployment of machine has been beneficial to men who once were labored to disability and death. The price of that benefit is that they no longer have a advantage due to personal strength and speed. I applaud the trade off, I prefer that men no longer be labored into infirmity.
