you can&#x27;t ignore &quot;legacy&quot; applications if your new technology needs acceptance and deployment first and foremost to get out of the toy stage.<p>besides, think of all the future cool stuff you can more easily build on top of rump kernel (almost a year in the IRC channel and I still can&#x27;t recall how I&#x27;m supposed to refer to...it) rather than being &quot;stuck&quot; with just Erlang on LINC or Haskell on HalVM etc.
