When I compare the "Hello" on the screen to the concept of "Hello" in my mind, I cannot hold the details of the character shapes in the same clearity as I do when I just focus on the shapes.

So the siutation with the two Hello's might be just as simple (My rough estimation: 100 bits) as the situation where I focus on the shapes.

That's why my feeling is that the lower bound for how complex the universe is, is 100 bits.

Let k be the fraction of the information contained in the original perception that you're able to hold in your mind. Regardless of how large k is, the universe maintains apparent consistency to the subjective observer, so its intermediate states between when you observe it and when you observe it again must be held somewhere, be it in the configuration of particles in a physical universe, or the memory storage of some mad scientist who keeps your brain in a vat and feeds it fabricated data. If the universe consisted solely of whatever it is you're perceiving or contemplating at any given time your thoughts and perceptions would not make sense to you, because there would be no consistency from one moment to the next. You would look at Hello, look away, look again, and see Bye. Even if time is an illusion and you only looked the second time, you would need to account for the fact that your false memory of a moment that never existed matches the perception that you're processing now.

I don't see any proof that time exists. For all I can tell, only the present moment exists. You say I "observe it again". But how do I know I observed something in the past? The memory is just an experience I have in the present moment.
