Does part 2 exist yet? This is basically an explanation of what FPGAs are and a "hello world" nMigen example.
That said, high-level HDLs like nMigen are very promising for education, and I hope more people take the same first steps as the article's author did. It's a fun field.
And along those lines, here's hoping that MIT updates their free 6.004 edX course to reflect the in-person class' new RISC-V focus soon.
