I saw it. Nothing new in there and no real details about the production of techeles. Mostly it was just some historical background about the use of blue dyes and a theory of why we lost techeles.
Then two arguments for the use of techeles 1. There was an ancient blueish dye that was produced from the murex snail and we don’t know of any other candidates for Techeles, so it must be this. 2. Why not use murex dye on your tzitzis on the possibility this is the correct source of techeles.
It was completely a one sided presentation, without objectively presenting the halachakic pros and cons of coloring ones tzitzes with murex dye.
