You own your brain in the same sense that you own modern devices, you own it but also can't really modify it and there is some closed source shit that really control it
Make our brains FOSS! Why can't I just tell my brain that now is sleeping time and it will just sleep?!
Your conciousness is literally a process of the brain’s proprietary code.
It's a likely hypothesis but we don't know that for sure. There's zero evidence of consciousness outside of your subjective experience of it. We don't know what it is and how it emerges.
I may not be real in the physical sense but the fact that it feels like something to be is the only thing in the entire universe that I have zero doubt about.
I'm not claiming that I or the world doesn't exist. I'm just aknowledging that that is a possibility. Who knows, maybe I do live in a simulation. This however doesn't take away the fact that it feels like something to be simulated. That is the undeniable fact of my subjective experience that cannot be an illusion. Everything else is up for debate.
Well, kinda. The brain is the hardware "the mind" is the software. If we could separate the mind from the brain we could upload ourselves somewhere to live forever. So IMO my brain is just where I keep "me".
