Average seems like a weird measurement. Some Forbes article claims by 2030 the world needs 68 million teachers (I had trouble finding how many currently exist).

Average seems like a weird measurement. Some Forbes article claims by 2030 the world needs 68 million teachers (I had trouble finding how many currently exist). So, the scale of numbers of teachers and number of engineers is hardly one to one. Maybe you could say : is the average engineer contributing more to humanity than 1,000 teachers? Or you could go by pay: is the average engineer contributing more than 10 teachers? (guessing on numbers of course) One to one ratio though? I'd argue: yeah probably. It's indirect effects, but Android/Chromebook/Google Docs... These all have brought computing technology and the internet into the hands of children around the world. Internet access is clearly one of the great opportunities for education. It might be hard to measure, but it clearly has an outsized effect.
