Your point only makes sense if you assume nothing has changed in the last ~50 years. Instead of asking questions which have already been answered, why don't you read the many reports describing precisely why some people believe women are being put off working in this sector? Your post has all the hallmarks of a sincere post, but the very fact you are posting it destroys the veneer of your objectivity. Plus you are talking about a single recording engineer. Just one. Amazing.
