[...] The self-healing polymer, created by researchers at the University of Tokyo, was initially discovered by accident while they were studying new adhesives.
During the research, one of the team noticed that the polymer he was examining for use as a glue had the ability to adhere to itself when cut, compressed and held together for 30 seconds at room temperature (21 degrees Celsius, or 70 degrees Fahrenheit).
[...] It's not the first time researchers have designed self-healing materials like this, but what sets the new polymer apart is that it's structurally robust, like glass, but also capable of self-healing – properties that are often mutually exclusive in engineered compounds. What also makes the glass unique is that it performs its self-adhering function at room temperature, whereas other self-healing materials often require heating to induce their bonding behaviour.

You mistake my point! It is not that recent tech is somehow inferior in general, but just that it tends to promote a forgetting of the technology of the past. Not suggesting that current tech should be forgotten! And besides, sheet metal is way too labor intensive without massive roller mills. In ancient times it was limited to things like armor plate. But nowadays things like forge welding are something of a lost art. And now we have hammer-welding of glass to look forward to!
