Not true. You must first understand what it means to be human.

Go to the tenth millennium bce, what was Man doing? On cave walls he drew his thoughts. What kind of thoughts? Outward events.

Now, many years later, Man is expressing himself on digital walls. What is he talking about? His inner self.

Tycho. Consciousness is not shared because there is availability of diversity of opinion, belief, orientation, attitude, and thought. All these divisions are incompatible and mutually exclusive with a singular universal consciousness. That a single unit of consciousness can transit from one division to another yes even extremes is not indicative of continuity of consciousness but rather the possibility of divergence. Separateneness.

Diversity doesn't necessarily mean lack of a shared domain. Look at bees, ants, swarms.

'I am' is a non-zero sum game. Language for example. It's always producing new words.

@symbols, language has more than words. There's also meaning. The words may not be new, but meaning is always created.

So language has both zero sum and non-zero sum elements in constant engagement.

'I am' is the signifier. The Creator of meaning. 'It', is the signified; the zero sum.

That's the only condition for saying, 'correct' and 'not correct'.

Revolution of consciousness is the awareness of the dialectic of 'I am it'. It's the difference between writing now, and our ancestor's drawings on the caves.

And the dialectic between 'I am' and 'It' is the spark of creation. The source of difference and unity.
