Not sure I agree with you there: should it not fork a process to run a heavy task? Should it not fork a process for each end of a pipe, especially considering we're deep into the multicore era of processors?
The fact that the basic shell could use more builtins instead of delegating everything to external processes (like calculating a simple expression) is totally unrelated to the Unix Philosophy being bankrupt.
If fork and processes weren't so expensive, I still think multiple processes are the best way to parallelise on multicore CPUs. In fact, there's a resurgence in programming environments based on multiple communicating, yet isolated, processes, see Erlang/Elixir.
Though I definitely would like to see someone seriously exploring a different paradigm than UNIX.
EDIT: Unix philosophy also is "everything is a file", and what is a file exactly? A bag of bytes. Everything we deal with is a bag of bytes if you think about it, so I find it perfectly fitting to model our world that way.
But then again, the current construct to represent this idea such as labels organised in directories, might be a bit long in the tooth and we're due for some paradigm shift on this front as well, but I digress.
