Coming to the "vids or it didn't happen" feeling, we totally get that as well. To be fair, we would've had the same feeling if we watched ourselves from a third person perspective. But we're actively working on bringing visible proof (benchmark is a better work) on the claims and promises that we're making. And in your analogy, the vids are coming soon, stay tuned ;)
We've scheduled a prototype launch later this year. We would make much more progress till then and the public would get proven answers from our side once that happens!
