Well there is a descriptive title on the video
It would be better, to write a nice summary, of what makes it interesting for you and perhaps others. Then others (perhaps hundreds of others), can quickly glance at the summary, and decide for themselves, if it sounds potentially interesting or not.
Rather than having to try and second guess what exactly it is about, from a very brief title or recommendation from a user on this forum, they may know very little or nothing about.
E.g.
Interesting documentary (for me, even though I've already seen it, at least once, a fairly long while ago) video. Which seems to be about an amazing production line machine, made/designed and built from very early 1940's technology, at around 1947.
Which seems to basically be a number of analogue (or similar) computer (elements or more). Which improve/control the process. Which makes these (what are similar to thin-film or other types of tiles/assemblies etc).
I.e. A sort of PCB (very early), but with films/coatings/chemicals etc, to make things like resistors, capacitors, inductors (I'm not sure of the exact list of component types) and valve/tube sockets, etc.
To effectively make a module, which is most of a full radio (of that time period), which just needs a few valves/tubes to be plugged into it, and the rest of the assembly. To make what amounts to a mass produced device, such as a radio.
Presumably, that creates lots of cost savings, allows much higher production unit rates (quantities), and with much less labour (costs).
It seems clever, for that time period (1940's).
