No one has demonstrated anything. SoftBanks portfolio has taken a hit, but it is hardly a nail in the coffin. Son's actions have generated enormous wealth gains for the people he backs, but in the end the public eats a majority of the losses. Son has still made billions and billions using this model, so how can you say it does not work? You would have to look at funds that tried this same thing and went bankrupt.
