That does not imply that the best male mathematicians or computer scientists were male: it suggests the most widely-recognized such were. That's like saying the best writers are mostly European because that's where most of the Nobel prizes for literature have been awarded. By the time you have gotten to that prize you have gone through a large number of potentially-biased filters. If men were better at running companies, companies that hired women would have worse performance, the opposite of what was observed. It is far more likely that men are in charge because they always have been and such decisions are made by humans with systematic cultural prejudices. In fact, such prejudice can explain gendered difference in advancement. For example, see http://www.west-info.eu/files/SSRN-id2018259.pdf http://www.west-info.eu/files/SSRN-id2018259.pdf about how men with stay-at-home wives denied women opportunities for promotion and saw companies that employed women as less successful than those that didn't.
