Return of the Lisp machine
Arto Bendiken notes that Lively Kernel is a reinvention of the Lisp Machine concept. For those who’ve not heard of them, Lisp Machines were really great pieces of work: at a time when command-lines and static software which crashed were the norm, they provided full GUIs, dynamic software and elegant error recovery. Perhaps Lively Kernel can bring some of that coolness into the 21st century.
Computing really is about continually reinventing the wheel.
