We went through a selection process when choosing our ISA and
ultimately RISC-V won out. RISC-V is behind OpenRISC in some aspects
(system software) but rapidly catching up, and well ahead in others
(such as regular tapeouts of high performance implementations). We
want to provide an SoC platform for others to build on and modify, and
starting out with a design that we intend to obsolete and abandon is
the opposite of being focused.

We're very aware of the challenges and the timelines involved in
producing silicon. e.g. we have a 128-core research test chip on a
40nm process taping out this summer. I'm not sure why you think we're
anywhere near running out of steam, on the contrary we're just getting
