If you read the new paper, one of the main properties of the new technique is that it does not affect the wood lignin, so that the final transparent wood has the same properties, almost, as the original wood. In this video you linked to, the techique involves completely removing the wood lignin (see 4:08). Clearly not the same thing.
Another huge difference: in this video, the wood is dropped into a boiling chemical solution for 12 hours. In the new paper, the solution is brushed onto the wood at room temperature, then the wood is left exposed to UV light (which can come from natural Sun light) for just one hour.
The video uses boiling, distilled water to wash the wood (for only around 15 minutes), then hydrogen peroxide (in an awkard attempt at removing the lignin left) after the chemmical treatment of the wood, while this paper just mentions using ethanol (5 hours immersion) to remove just the chemical solution from the previous step.
The video mentions that after all this, the paper it's based on says they still need to boil the wood into a 8% peroxide solution (the video author decides to use much less, though, at 3% due to "foaming" problems) until the wood turned white, after which they use ethanol to remove the chemicals. In the new paper, this step doesn't exist at all. The UV light is enough to achieve that and the wood had already been washed with ethanol.
Only the last step, using vacuum to infiltrate epoxy into the wood, seems to be similar between the two different papers (though the author of the video did not have a very good techique to do that... both papers are quite lean on details, so the author of the video can't be blamed here).
I mention all this because you and other people in this thread are choosing to dismiss this new paper based on a video about a completely different paper, using a totally different methodology, which shows that you're either trying to intentionally present misinformation to HN readers, or that you didn't bother to read the new paper at all and just assumed nothing new in it.
Please avoid such behaviour in public forums, the last thing we need is more disinformation and lack of depth in our dicussions.
