Let me ask you.

You have a budget of 24 Billion transistors (& a much more limited
power budget). How would you spend it to maximize general purpose

Note that Esperanto Tech. was founded by Dave Ditzel, not exactly a
h/w newbie. [EE/CS, worked with Dave Patterson, CTO @ Sun, Transmeta
founder etc. etc.]. Now it is entirely possible that Esperanto folks
are building such processors for special purpose applications like
Machine learning but the fact is we simply have an incredible riches
of transistors that we don't how to spend wisely, [My opinion, of course]
