"Double, double, toil and trouble"... Shakespeare's words (Macbeth, Act 4, Scene 1) often cover circumstances beyond his wildest dreams. Toil and trouble accompany major computing transitions, even when people plan ahead. To calibrate "tomorrow's legacy today," we should study "tomorrow's legacy yesterday." Much of tomorrow's software will still be driven by decades-old decisions. Past decisions have unanticipated side effects that last decades and can be difficult to undo.

I wasn't familiar with Bluespec, but it seems to address the technical issues.

Still, the larger issue of getting CS guys and hardware guys to agree on specs in the first place seems like a bigger problem.
