Bolding points doesn't mean that you haven't left out important caveats that are required to give your hypothesis some merit.

Would you like some lovely crayons?

This is a little bit off, common thought seems to be that the way the brain stores memory is through association, not direct record/replication.

If you walk into a room 400 times you don't have 400 recordings of the room, you have one, which the brain alters and updates accordingly depending on changes made to the room...the changes then overlap...but the memory of the human brain is basically transient and ethereal, it's not static.

Is this the reason that when one of my friends gets a haircut I can't remember what they looked like before?

Our brain is not like a hard disk at all though... it's apples ans oranges.

Bah, I use cloud computing also known as the ether.

Funny thing about memory...every time you remember something, your brain rewrites it, which keeps it 'fresh'. If it does this enough times, the memory (neural pathways) becomes more static..i.e, it becomes long term memory. But even these long term memories degrade over time if we are not actively reminded of them, which then 'rewrites' the memory. And events that only happened recently can have gaps as well, as the brain only tries to retain relevant information...it deliberate forgets most of what we sense.

The brain has a great way of dealing with this. It fills in the missing bits with 'likely data' based from other long term memories.
If you ask 5 people to exactly describe an event that happened just a few hours ago, or many many years ago, you will get very different recollections because of this. So oddly enough, for most cases, the memories from a few weeks/months ago that are 'important' are actually our more accurate memories.

For evolution, it makes sense. Information we know longer regularly need is forgotten over time, and things that just happened are only put into long term memory if we see it as important or use it a lot.

So, for this reason, memory capacity probably won't ever be reached.

Incalculable in real terms.
The brain is incredibly good at compressing data and not the same way that computers do

So looks like he's using something like Nand Flash and going up to 4 bits per cell.

http://www.theregister.co.uk/2012/02..._bleak_future/

For example, our data show each additional bit-per-cell increases write latency by 4X and reduces program/erase lifetime by 10X to 20X, while providing decreasing returns in density (2X, 1.5X, and 1.3X between 1-,2-,3- and 4-bit cells, respectively).

Ah here you seriously cannot compare the brain to even the most advanced super computer. For one they have a fairly good understanding of how a computer works.
