I say that I have free will because my decisions come from myself and not from something outside me. Sure, the context in which I live can influence my decisions, but the final choice is mine and it can happen that I take a decision that goes against what the context (society, family etc.) would expect from me.
I mean you've got a body, too, right? So the moment the environment changes so does the mind state. So unless you've come up with a method of modeling all of those influences... And food, and hormones, and... And then you've got stuff like cosmic radiation slamming into your DNA causing dsDNA breakage and that precipitates into apoptosis and suddenly the model is off due to some completely unpredictable shit, 'cause were talking about interactions that are occuring on the scale of 6.022*10^23 per mol, and a lot of mols and a lot of different species of matter themselves subject to probability moreso than determinism at any reasonable scale.
If sufficient technology were to emerge, I expect that under no circumstances would it ever be considered as a worthy project to invest in. But the idea of such technology ever emerging itself is frankly worthy of ridicule.

This is assuming that intelligence is computable, but no one has proved it yet. And doesn't even get into the problems of quantum physics. Unfortunately, the real illusion is determinism.
I call this the "subjective experience of free will": that is, it does seem to be a thing that people perceive, and it's such a convincing effect that we often turn it from a subjective experience to an objective belief (that free will exists).
Sure, I never said I have an objective proof. But there's no proof of the contrary either, so the two positions are at the same level, objectively speaking.
Yes, I had the same discussion a couple years ago and I concluded it by saying that it boils down what's myself: is it my brain? My consciousness? My soul? But this is a related but different problem.
I would say it's a measure of probability. Of course measuring probability in non repeatable situations gets tricky.
But, if I wrote there is a 90% probability that lupire will write an application to 'beat' the free will program, and then you did so, it should at least give you pause.
Even a Turing machine has free will. You can’t find out what it will do without running it, in a way beyond all questions of technical capability. Mechanistic attacks on free will died with godel.
