It probably has more to do with millions of male soldiers reentering the workforce around that time. The idea of "gender roles" still had a grip on society and women were forced out of their wartime careers across the country. The only reason they had a chance to take on all these previously male dominated fields was because sixteen million Americans had to leave the workforce to fight a total war. The GI bills provided a ton of financial assistance to WWII veterans seeking a college education, which explains why women had a little more time in advanced fields like computer science. Due to cultural mores the wartime trained women were bound to be replaced by men, especially in the armed forces, it just took a while after the war to educate the soldiers.
