Subject: [alt-beam] Re: BEAM classification


Alittle off topic but... In one of my dumpster dives I came accross some old
mother boards including cpus and static ram. My understanding of the more
complex issues of electronics is sorely lacking but, would you consider a robot
that uses a cpu and ram and a language like LISP to be beam? LISP is recursive
and it is possible to create code that can change itself due to the FEEDBACK it
receives.
