Not so much interesting, but it rather looks grossly inefficient and a complete antipattern in terms of data layout, unless Erlang has a very, very capable allocator, that is able to correctly colocate all these linked structures. Still, th

Fully agreed. The observation that SQL still works as well as it does today as it did in the 70s suggests that it's a good and valueable abstraction.

Counterpoint to complexity: Simple CPUs (scalar, in-order) are likely less complex than the TPU. E.g. here's a super-scalar in-order core: https://patentimages.storage.googleapis.com/US6311261B1/US06... > I bel

I'll bite: In which way is a computation engine (CPU [not ASIC], GPU [ASIC], Xeon Phi [ASIC]) more general purpose than a computation engine for AI [ASIC], GPU [ASIC] or Xeon Phi [ASIC, even though some of these are usable as a host pr

Memory controllers are not so simple to do, and fast MCs also eat quite a bit of power. So a simple reason that they didn't do it could be either a) they did not want to license a more expensive, faster design b) while it would be fast

Most accelerator-esque chips are often considered some kind of ASIC. CPUs are not ASICs because ??? ... never heard a good reason there. It's a fuzzy (but not fluffy) term.
