@Lex Fridman if consciousness properties of particles are orthogonal to the physical properties of matter, and complex consciousness can be derived from the basic conscious particles, that would imply that no consciousness can have any impact on the physical world. I find this a hard pill to swallow because it seems that the world we live in is shaped by consciousness day by day – how else can we explain advancements in technology? How else can decisions be made; to couple with one mate or another, or to choose one design implementation over another? Our present experience is continually shaped by our visions of the future. This is why it's necessary to take the stance that the physical properties of particles that we observe ARE properties/expressions of consciousness.,(reply>), @kyjo so your stance is that of absolute materialism, that consciousness is an illusion that plays no part in the shaping of the world? If so, more power to ya but that's not a stance that works for me.,(reply>), "how else can we explain advancements in technology?"  --- As a continuation of evolutionary process? Come up with new stuff more or less randomly and see what sticks.. And it's not like "visions of future" just come out of nowhere. They come based on past experience, memory. Whether it is stored in our brains, or in DNA.
