People always complaining about the cost of the dev board or about how they can't think of a practical application. Maybe those are valid criticisms, but honestly we have something unique here, try not to dismiss it with vapid complaints. This computer and the engineering culture from which it comes is radically different. It's more efficient then anything else I've seen. Sure, it makes some things more complicated to program but makes many other things vastly simpler. It enables a level of software control that approaches the functionality of an FPGA yet retains the interactively of a fully software solution. And it's fun to program, and simple enough to understand everything about it. I wish we had more computers like them

Erlang is a high-level language ideally suited to concurrent (not parallel) computing on multiple cores.

Is there any kind of cross-over here, with GreenArrays processors? Is it feasible to have an Erlang VM running on a GA chip, and would it have any advantages over the current (typically x86) hardware?

(From the Erlang website (http://erlang.org/faq/implementations.html): "Getting Erlang to run on, say, an 8 bit CPU with 32kByte of RAM is not feasible. People successfully run the Ericsson implementation of Erlang on systems with as little as 16MByte of RAM. It is reasonably straightforward to fit Erlang itself into 2MByte of persistant storage (e.g. a flash disk).")

Another question: the computing demands of self-driving cars are somewhat self-defeating (https://www.bloomberg.com/news/articles/2017-10-11/driverles...). Isn't low-power computer vision a perfect match for GA chips...?

No chance of that, GreenArrays processors are arrays of f18a computers - each of which only has 64 18bit words of RAM. Orders of magnitude less then Erlang requires. I would start with the product briefs if you want to learn more: http://www.greenarraychips.com/home/documents/downindex.html
