Honestly, you really do not give any sound technical reasons as to why XRB will fail. Your main point is that it will not get adoption, but that is a problem for all cryptos right now. The argument that you are making here could be applied to almost any coin that is currently rising through the ranks.

In your video, rather than critiquing the technology in a direct and logical fashion, you completely dismiss it saying "I don't care if it is perfect tech, it can never get adoption." That's a strawman fallacy. The tech is everything at this stage. It is the hardest part to get right. Making fancy websites or pretty marketing pictures/mobile apps is trivial and can be done by monkeys and college students. And this is coming from a real world, full time software engineer who lives and breathes it every day. The real value is in the core tech behind the block lattice. That is the hardest part to theorize and implement.

All of that said, there are some legitimate problems/unknowns with the core tech right now that you could have addressed had you been educated and informed, which you clearly were not when you made this video. For example, there may be a way to possibly ways to compromise the network with spam attacks (currently being worked on by a dev) or a 51% attack. Both of these types of attacks are addressed in the white paper and are real threats to the integrity of this currency. But, instead of talking about anything concrete or technical that is unique and specific to the Raiblocks project, you simply spew a bunch of nonsense about adoption which is something that the entire sector is currently struggling with.

It is a shame that someone with your level of influence could not put together something with more substance.
