SoftBank CEO Masayoshi Son: Tech visionary or mediocre capitalist with too much money to spend?

Arrogant and over-confident are more like it. He's gambling with $100 billion of investors' money that will never yield what was promised - crazy big returns beyond logical reason. He's basically artificially pumping up private companies that are loss-making and then trying to dump them onto the public in the hopes of massive returns - unfortunately for him with WeWork many people have caught on to the scam.

He invested heavily in We Work despite a million warning signs and that pretty much blew up in his face.

Not sure if he saw something everyone else was missing, but seems everyone else was right.

Not sure if he’s gotten lazy, but definitely too sure of himself to do the proper due diligence.

agree with bill. He's both. more of the latter in my opinion

I'd say both. He had a vision for Softbank after he bought out Vodafone Japan, but became mediocre when he made more money. His wealth made him lazy.
