Thanks for your thoughts. The transaction fees are negligible and only there to protect against spam attacks. I also have faith Ripple can scale easily in the event that they need to. I will say the opposite of you - that's not to shill Ripple, but rather to look beyond what is now into what could be. Furthermore, often tech is not the deciding factor of success and this is not true in only cryptocurrencies. New generations of technology will always outperform the old, but it is often difficult to replace them in terms of adoption. Not to start any fights, but I think the fact that Apple is the largest, non-state owned company in the world is a perfect example of why tech is not as important as everyone thinks it is.
P.S: I don't know much about Raiblocks yet, so am just taking what you say at face-value.
