There are LOTS of computing devices that have NO code in them. Rather than harnessing ALUs by feeding them data under the control of an instruction decoder, you can cascade them, feeding the output of one into the input of another, to do entire loop iterations every clock cycle. Doing such things is NOT "programming" in the usual sense.

Simply institute a six hour workday. That will easily create enough new jobs to bring back full employment. ------------------------------------------- AGI Archives: https://www.listbox.com/member/archive/303/=now RSS Feed: https://www.listbox.com/member/archive/rss/303/21088071-f452e424 Modify Your Subscription: https://www.listbox.com/member/?member_id=21088071&id_secret=21088071-58d57657 Powered by Listbox: http://www.listbox.com
