Future prediction possible : What do you "think"???

This is in continuation to my earlier theory /* refer to "My unified theory of so-called living and non-living", two posts below this one*/ So, if we consider this to be true, i mean, if we consider that we donot think as such, then i think that in such case prediction of future is also possible. If we can predict the output of a program by dry run, we can also predict output of the machines called homo sapiens. But this is only possible if our thought process is guided by some kind of algorithm, though highly complicated. At times I do feel that my decisions, they are governed not by me, but by others and my genes, just like a program, where input is given, in our cases things happening around us, and the algo followed, here our genes. Welll, here I havent used our brain yet, but brain is also, what I think, ultimately governed by tiny cells, which react according to their own brain, called nucleus, where we have chromosomes. At this point of time, lemme make one think clear, I am, in this post, not explaining you what I have concluded, but what I am pondering upon. So, dont worry that only you are getting confused, I am even more. So, lets continue, where were we.. Ok, first thing is do we really think or is it just some kinda programme thats going on all around. If its just a programme, then I think that future prediction is possible, though it may involve really complicated calculations which may make it practically impossible even for 100 super computers, but it will be possible. But it will be a totally different case if we also do think and make decisions on our own. I do think that it could make a difference between humans and computers. We can call it randomness or sometimes spontaineity. If we do posses that, then I think we can really consider ourselves a class apart from all those dumb machines. This thing I am not able to figure out, do we really make our own decisions or is it just our genes and surroundings that are controlling us??? While I was just pondering upon this question, I thought of analysing my thought process and decision making processes. Though I havn't completed that yet, still I would like to share what all I have till now. While making any decision, what all I do is to collect all the inputs, and then I see what output will I have with any particular decision and select the one with what I consider to be the best output. To asses the outputs, I do something what could be called calculating weighted mean. I do things of that sorts most of the time with inputs also. Like which factor should influence my decision more. Then calculating positives and negatives and then I do go a decision with more positives. Actually, this is not much complicated as I have narrated, this is really simple when you have to make a binary decision, and I think most of the times we need to make binary decisions only, like to be or not to be. Then its really simple, calculate weighed mean, at times its better to calculate total than mean, choose the decision with greater positive value. Doesnt the last paragraph seems to be a bit too mechanical. I do think so. It makes me feel more like a machine than a human /* though humans can also be machines*/. I really feel like not to be mechanical. I want more randomness in my life, more spontaneity in my life. For that, I have made a few changes in my lifestyle. One of them being not planning for things less important. I think enough of crap in this post, rest in next, dunno when.
