Personally I also preferred the ‘Everything is an object’ from the lisp machines. However, I also believe that files are an acceptable object format, since if several applications know how to manipulate a file format, it’s basically duck typing. I believe file systems could have a more formal method to query the file’s format, and has less latency so that applications could use files as an inter communication format.
