That's a huge job, they must have someone already acting in that position considering the stage that they are at now??
Just a thought, is the "top 5" identity still an elephant in the room?
If it is, then, one would think that, as they have apparently only purchased 3 platforms, conditional upon confidentiality, that If they were to purchase any more platforms, that would represent a "material" matter and require a TH before it is announced, and the identity of that "Big 5" company would also be able to be released?
I've thought for a while that the Big 5 might just be a training ground, as, my guess, Amazon, seem to have AI fully under their own control. But, if that Big 5 still is a player, then, watch out, as, surely, they will be needing more platforms after so long, (if they like it of course)!!
