Was it paid by Coinbase?
Peter Todd was the primary driving force behind the creation of the vid to the best of my knowledge, and I personally contributed significantly in a financial sense.
Probably the most important take-away is the image of a transparent processor where operations could not be hidden (if there were market demand for one.) Coinbase is absolutely
not in that category and to this date no real implementation of such off-chain solutions displaying this characteristic really exist, but I must admit that there well could be some which I am not aware of since I don't pay that close attention. One way or another, it is fairly easy to balance risk between off-chain providers and core holdings. No matter how shitty the off-chain implementation the option always exist to do this sort of risk balancing and this largely blows the ubiquitous argument that off-chain providers cans steal all your money out of the water. Even in the worst of circumstanced they can only steal what you let them.
Contrast this with the ability of an entity to steal one's money via fungibility attacks on Bitcoin itself such as blacklisting/whitelisting which is an across-the-board attack. It is also, parenthetically, something which has characterized Mike Hearn's interest in Bitcoin since at least 2011. Ponder on that a little before 'upgrading' to XT. Or don't. I'm actually not totally adverse to having the Pied Piper lead a lot of you idiots away and Bitcoin will be the better for it.
The video was made before there was any real discussion of sidechains and the 'two-way-peg'. Also before crypto methods of having transactions 'revert' such that not only could it be the case that an off-chain provider could not take your money as his own (which would solve 99% of theft problems in and of itself) but there likely are ways to have it so that you could eventually have your balance restored. Or even more if the off-chain provider posted a bond which, again, could in theory be validated via transparency in operations.
Between nearly perfect proxy behavior for the Bitcoin circulation base, transparency, and crypto-extensions which significantly mitigate the counter-party risk, and the breadth of mutually conflicting niches that purpose tuned off-chain solutions could serve, they are hugely promising. Those who would attack Bitcoin have no choice but to do it quickly before sidechains come on-line even if their attacks are pre-mature. It's the last best hope.
