This seems like shifting rationalization to me. They used to say women don’t want to be lawyers because it’s too much confrontation. Now women are well represented in law because it’s people oriented. Moreover, corporate law firms are 50% women, but that work is even more solitary than programming in a corporate environment. (Having done both myself.) You’re sitting in your office alone reviewing documents, writing briefs, or doing due diligence ten times as much as you’re in court or talking to clients.

Also, if programming is solitary as you suggest, why do tech companies discourage remote work and insist on culture fit, team building, collaborative work spaces, etc.? Much more so than law firms.
