Why is it up to the marketplace to close this gap? If few women are going into the STEM fields, how is the tech industry, or any other industry, supposed to make up for the imbalance? It is the responsibility of parents to instill confidence and foster curiosity in their children, and up to educational institutions to exploit and encourage that curiosity. If there are plenty of qualified women applying for these jobs, then shame on the companies that willfully neglect the opportunity. If there are very few qualified women applying, then don't punish an industry for the failures of parents and educators.
