For more than the past decade, Bill Gates has dabbled in education. He launches initiative after initiative, with slim or no research, and all of them flop. While he dabbles–whether it is the Common Core or evaluating teachers by test scores–he messes up other people’s lives with no accountability for his screw-ups. He just moves on to his Next Big Idea.

Mercedes Schneider points out that the Gates Foundation spends more money “reforming education” in the U.S., but has nothing to show for it.

Curiously, the Gates Foundation’s annual letter doesn’t even mention education! (Correction: Leonie Haimson pointed out that education was not mentioned in the Foundation’s annual letter; its annual report is not published yet. So maybe we will hear some Trump-style claims about the successes of VAM and charters, and other DeVos strategies for privatization.)

Will he butt out? Will he admit error?

I saw him on TV Saturday night warning about the dangers of bio-terrorism. A few weeks ago, he met with Donald Trump in his golden penthouse and came away expressing admiration, prophesying that Trump had the chance to be transformative, like John F. Kennedy, by driving education innovation with new technologies. What’s on his mind? Saving humanity or market share?
