I think the response Magic Leap is getting is quite similar to what Tesla has. Even when they have demonstrated prototypes and close to production, naysayers still keep publishing content as to how it will fail eventually.
I trust the judgment of these big companies that have put $1.4 bn in to this company. You need to sign an NDA with the company if they even consider you for an interview. I am guessing if any of these so called disclosures were true, the guya responsible for them would be facing lawsuits, I guess they should be facing lawsuits anyways. Also, Oculus Rift is a parallel example even though they were close to releasing a product before being acquired by Facebook, they still took more than an year after getting the cash infusion from Facebook to perfect their product and that is what I believe is going on with Magic Leap as well.
