I think you are missing the point. In order to support massive
parallelism, data must be duplicated as it comes of the wire and into
memory. Not duplicated in FIFO streams in an application. The latter
is a software implementation of a hardware task and is consuming
resources.
It requires hardware and architecture changes to implement properly.

I think you're still missing the very-important point that Gnu Radio
doesn't duplicate the data. Blocks that share an input share a ring
buffer, with
each block having their own pointers into that ring buffer. There's
no copying on the input, and work functions have a "contract" with the
scheduler
that they don't modify their inputs, thus guaranteeing that sharing
the input buffer is "safe". There are some pointers that move around, but
a bifurcation of a stream simply means bifurcation of pointers, the
data aren't duplicated.
