> If you or your retirement is a shareholder in one of these companies, you'd rather they return $100 billion to you with boring buybacks or dividends than put it in an exciting AI investment that returns $1-$10 billion. Even though it didn't end up completely worthless, it's still a bad investment.
As a shareholder I'd rather them take the $100bn and invest it in growing the business further and generating $200bn. That's the more likely outcome anyway.
