Dataflow processors have not been forgotten - there is one inside every high end CPU core. The code in main memory in the form of conventional x86 or ARM machine language gets translated first into "micro ops" in the decoder and then into dataflow machine language in the register rename + reservation stations + completion buffers (collectively implementing "out of order" execution).

But, as the old saying goes, "out of sight is out of mind".

Oh, I don't think at all that this method of operation (Tomasulo?) is remotely close to a real dataflow in terms of efficiency and complexity. But as I wrote, dataflow is another story ;)
