Yeah, strong agree here. Nielsen brought a certain weight of rigor to the debate back in those days which made sense to the way I wanted to think about web design as an engineer. I don't really think there's a "winner" or "most right" person amongst the trio, but Nielsen's ethos appealed to me more than the others mentioned.
Lots of social commentary here, but I'd just note you're one mad lad. This is a great writeup and a nifty bit of sleuthing. I found it enjoyable to read.
Got a little beat going with it, but the lack of VSTs and fine-grained control will be limiting in the long run. It's a super cool in-browser demo though. Overall, I'm very positive on the efforts.
Lots of comments herein cover things I would otherwise post, so I'll just say this is great fun. Love that it's FOSS. Now, everyone go make some music!
