We have free will, but are limited by our means.
We aren't be guided by inescapable fate. Sure, things in our society can influence it and make certain things easier or harder to achieve. Or something more or less likely to occur. But I think it's silly to think it's all predetermined. We make our own fate and our ambitions and ability determines how far we can take it.Even if we were stuck in one inescapable path, it can't be proved or disproved and you'll never know. It can't be tested so it comes down to each person deciding what they believe themselves based upon feelings, and not factual data.
I look at a belief in some predetermined fate as surrender or capitulation. A sort cowardice to succumb to the belief you're powerless to change your life. Like it's an excuse to accept things the way they are and saying "oh well that's how it is" instead of doing what you can bring yourself to do.
It's not much different than asking someone their beliefs in Transporter technology. It's what you want it to be. If you were transported Star Trek style from where you stood to 3 feet to your right, some would say the first you is now dead. The act of breaking your atoms down into energy and reassembled anew in a new location "killed" you and now you're someone else. The same memories, body, DNA, the same in every way. But some would say you're a copy and not the real you.
What if a copy of everything you held to be "You" was installed into an amazing detailed and complex robot body, so advanced that it would be impossible for even the people closest to you to be able tell the difference. Is the copy alive, because it now has sentience? Or no, because it's just a machine imitating it, albeit flawlessly?
Then one could turn around and say you're an organic machine with so many bits and pieces that is so advanced that it became sentient and is aware of such a topic and can ponder it's complexities?
You can say we're just machines that emulate life, but life is a concept we ourselves have invented as a result of that sentience. Choose how you want to believe it, but choosing one way or the other in itself will probably affect how your life plays out.
If all of reality is predetermined, what would be the point? So is it that, or is it a story is always being written as time goes on. And at what point should you care about things beyond your comprehension or ability to influence?
