I liked your video because you make an intelligent argument and you are not afraid to speak your mind even though you know your opinion will not be popular.  Please don't change.

Having said that I don't agree with everything in the video.  I think you argued that scalability is not as important as other factors, particularly adoption, and that UI is holding back adoption of crypto in general.  I agree with that.  You gave examples of Bitshares and Steem as cryptos that can scale as well as RaiBlocks which makes XRB essentially pointless.  I think that was the basis of your argument (correct me if I misunderstood) but if so I don't agree with it.  I only heard of RaiBlocks for the first time when DataDash did his YouTube video a few days ago.  I bought a few XRB to try it out for myself, and honestly I wonder if you actually did the same before passing judgement.  What blew me away was how easy and quick it was to open and use the web wallet.  If you haven't done it please try it. In fact if you send me your receive address I will gladly send you a little XRB to play with.  You talk about the importance of UI and that is a strong argument in favor of RaiBlocks right there.  I am not saying that it is a finished product, and there is certainly room for improvement,  but it works.  

RaiBlocks is about transfer of value.  I opened the web wallet and created an account in a couple of minutes (raiwallet.com).  I opened a second wallet and transferred a small amount of XRB between them, and sent it back again in a few seconds.  No fees.  Extremely fast. No waiting for transactions to confirm, so the value is immediately spendable.  Dead easy to do.  It just works.  Now try and to that with Bitshares - it makes my head hurt just to look at the UI.  No idea if you can do that with Steem but I doubt it.  So for me your argument about UI should be a vote in favor of RaiBlocks and I would not be so quick to rule out the possibility that there is a valid use case for it.  I don't believe Bitshares and Steem are RaiBlocks killers.  I am not saying that RaiBlocks is a Bitcoin killer (or anything else killer) but I do think it should be taken seriously.
