Picture it. The scene is Silicon Valley. Suddenly an investment firm materializes on the scene and starts writing checks bigger than anyone is accustomed to seeing. Fellow investors start to privately complain. Its partners are poseurs, they say. The firm is driving up valuations, they continue. It’s going to ruin venture capital, they conclude.

It was said of Andreessen Horowitz when it burst onto the scene in 2009. (Remember its then jaw-dropping decision to hand GitHub a $100 million check in 2012?) Today, it’s being said even more widely about the SoftBank Vision Fund, and little wonder, given that SoftBank is fast plowing $100 billion into mostly venture-backed companies and that, according to its CEO, Masayoshi Son, more $100 billion funds are coming soon.
