I think ML will eventually be part of FB, MS, Google, or Apple, or even Amazon within 5 years. It'll be another 5 before AR is mainstreamed.
Google seems to have had some decent experience lately with hardware, Amazon still feels like it flounders a little in this area with failed fireos phones, and alexa/echos' and maybe firesticks are the only major things they've really come out with that stuck, I guess kindles too a bit, but not great.
Samsung I guess could also be another contender to buy them, they put out some great devices as well... I don't know who it'll be - but I think ML will be acqui-hired.
With the arguable exception of MacOS X, I don't think Apple has ever just outright bought major products.

I mean, I feel ML team is definitely worth more than Whatsapp, but they don't have a product that's ready for mainstream yet... having the full backing of one of the bigger companies could bring mass AR to mainstream audiences faster.
