Regardless of whether Magic Leap is a Theranos level scam (and I personally think it is), this is additional evidence that there are massive amounts of investment money available out there.
Also, Theranos was lying to the general public about very important health issues that affect your daily life. So far, Magic Leap hasn't released a single product. Even if they do, at worst it will be a computer that isn't as good at playing games as they claimed it would be. Not really even in the same league as Theranos.
