I agree. The section on web browsers mentioned that Nicola Pellow joined a team of 19 developers at CERN. It doesn’t say that she was the only woman on the team, but since she was singled out that is the way I interpreted it.
It’s a bit hard to say that web browsers would not have existed if one out of 20 team members was not there.

I strongly recommend [Language Transfer ](https://language transfer.org). The best language course I have ever done, and I have done many (I speak five languages, at varying levels of fluency).
They have an app, that is simple, streamlined, and very functional.
The app also has also an Introduction to Music Theory course which people say is very, very good.
I think that you are off by about an order of magnitude. Spotify pays $0.003 per stream, and title apparently pays $0.01 -0.05.
