The machine only has pcie4x4 so 50Gb bandwidth, pcie3 would halve that to 25Gb
Thats the problem with these AMD laptop class cores, they have very little IO. They have been saying they will release in a desktop form factor, but then it probably wont have such good memory bandwidth...
The Nvidia boxes have 200Gb ethernet thats much more useful for clustering.
The corporate environments were here too, most companies used to run on Windows server. 20 years ago companies used to pretend they didnt use Linux, but they were, it was just introduced to places they didnt know about, as it was free so it didnt have to go through purchasing. The rise of the early web in the post dotcom years was the catalyst, Perl, PHP, Linux servers etc. Before mobile, that did bring back proprietary development to some extent, for clientside. That was the era when Microsoft said "Linux was a cancer". Many companies still have large Windows (dot Net pre dotnet core) codebases, but Java mostly runs in Linux now.
The language barrier is interesting, there is more Chinese open source now too, but yes so much is English. I remember using google translate for Nginx from Russian back in the day, and openresty from Chinese, but yes we are lucky,
It is 2x200Gb/s physically but the PCIe bandwidth is basically only 200Gb/s so it may as well be one, and actually its a weird 2xPCIe4 not 1xPCIe8 so it appears in software as dual 100Gb/s. Its a bit odd.
This paper (from the same research as his book on high end culinary organizations) is worth a read https://journals.sagepub.com/doi/10.1177/0001839214557638 - he talks about "negotiated joining" which is a similar scheme for placements that works well with undefined job roles.
This is exactly what Apple has done, but it does mean soldered memory, as socketed memory at these speeds still hasn't happened. In the server market that is pretty unpopular (even the hyperscalars are apparently reusing DDR4 with CXL in newer machines). DDR6 apparently has twice the memory bandwidth of DDR5 so that will bring it back in line, to around 1TB/s for 12 channels, so comparable but still with standard memory sticks.
