I would prefer they remain, because at this point Windows is the only (major) OS retaining a professional look and not giving in to the toyish rounded corner appearance. (Yes, even KDE is going that way in an effort to be trendy.)
Too bad the article mentions "Rounded corners [...] are also planned."
This article gives the wrong impression. High Bandwidth Memory (HBM) is a specific term where DRAM and main chip is packaged on a silicon interposer. This allows for a 1024-bit bus to be routed within the silicon interposer. This is not possible with a regular substrate. The DRAM on the M1 are just LPDDR4X-4266.
As an FPGA dev, I tend to think of HDLs akin to HTML than “code”. It’s just a DSL to describe a graph. Actually pretty similar to how tensorflow is designed.
