Are they actually doing good work, or is it just marketing? My only reference is Watson, which... was hyped out the wazoo... and isn't state of the art.
Good work in the R&D and strategic acquisitions? Definitely. Not that long ago they announced a significant breakthrough in scalable quantum computer architecture that will allow them to create faster and faster quantum computers. And the fact most people didn’t even notice is exactly what I mean by tripping themselves.
With respect - are you sure? Do you know this space? I don't know enough about quantum computing to be able decipher bs from legit work. I do know there have been pronouncements for a decade now and not much reality.
