To go extreme, wafer scale silicon - 900,000 8 bit cores, 120GB sRam. Hand wave on the 8bit for now and just think how to handle facebook or e-commerce. A static site is simple if it fits inside 120GB, but facebook is low write high read (Inassume) - but fetching from / writing to memory - making that parallel means rewriting a lot of things .. and e-commerce - suddenly ACID does not parallelise easily.

I mean this all seems doable with fairly fundamental changes to architecture memory concepts and … rdbms is challenging.

But I think we are way past the idea that a web framework author can just fix it - this is deeper - a new OS a new compiler and so on - but I could be wrong.
