I am a direct measurement type for several reasons:
1) I believe in the Missouri principle (show me)
2) I and many other have been burned by people's claims for hardware
3) Simulation has many draw backs: call them limitations or tradeoffs,
you don't trade off in reality.
4) Direct measurement can show interactions which simulation, etc.
can't show (especially when asynchronous things take place on sequential
simulations).
5) Lastly, consider the following situation posed by a comment once
given to me: "Gee, you simulate flying by those outer planets so
well, that we don't need to fly spacecraft past them......"
