If you'd like your thoughts to have any kind of value at all, why not show some work for b and c?
Bring some evidence to the table instead of just your feels.
I'm sorry. It so obvious to me that you do not have computer who can handle 24 GB block every 10 minutes. And if you think you have or you WILL HAVE (in next decade) then it is like debating with 5 years old child.
Did you notice when you shifted the goal posts, or are you not even conscious of the manipulation?
In what way is your original statement relevant to my computer?
"b) current technology cannot handle 24 GB blocks (and will not handle any time soon)"
Your answer was that it is my feeling. So show me computer what can handle 24 GB blocks b/c I have never seen any. (maybe NASA has some supercomputer)
