This surprises exactly nobody at this point (see my previous notes), but there will be much wailing and tearing and armchair strategizing as the entire industry tries to find some tea leaves to divine what this might actually mean for the ongoing siege to Intel and (most importantly for me) what the server landscape is going to look like, now that NVIDIA can put together entire systems from the networking hardware (Mellanox) on up.
The UK, also unsurprisingly, is just going to let this happen. They barely understand public health, let alone technology IP.
Update, January 2022: After much toing and froing, Bloomberg reports that NVIDIA might be walking away from its $40B bid, which is tied up in various approvals (or lack thereof). Which I actually believe to be a good thing.
