What is science founded on? If free will was an illusion, Galileo couldn't say "I dropped the two balls ten times and they always fell at the same rate, so they will always do so in the future". This is because he might have been at the cycle where the balls fall at the same rate ten times, but only those ten times. If he had free will, Galileo would seem to have more statistical evidence, but not if compatibilism is true.
Science seems regular when we are making phones and such. But even then, philosophy would seem to say that this could change at any moment, if only because other laws could kick in at any time. This causes special problems for cosmology, where they try to rewind the laws of physics. There could be infinitely many laws we don't know about that totally blur what happened in the past. So we can and should try to make cell phones, but saying we know thru physics what happened in the past seems to be an absurdity
