Sure, and I'm saying, we have no guarantees there are more dimensions, so to operate without some level of materialism (i.e. storing good ideas for future generations), just in case, is delusional. 

You think you know for sure there are other dimensions. I'm saying that's possible, and the opposite is also possible. It's not knowable to any of us. 

Therefore I store my ideas on chain in the hopes that it might benefit future generations. Regardless of if there are other dimensions to reality or not.
