But I/O being the bottleneck never was about sequential reads, was it? I get the point of the article, though.

With modern CXL/PCIe, I guess it's not going to be that stupid to claim that RAM/memory controller is slowly becoming I/O on its own.

Old IBM's term for RAM was "storage."

When I took my first database course one topic was IO performance as measured in seek time on regular old hard drives.

You can’t really optimise your code for faster sequential reads than the IO is capable of, so the only thing really worth focusing on is how to optimise everything that isn’t already sequential.
