Since when does somebody have to justify their premise to ask for advice?
This isn't asking for advice, this is forwarding an argument (" I think not being aware of the science behind such yesteryear technologies (or their histories) is not right.") without giving any reason as to why. You would think something posted alongside articles on current events including international politics and advances in science, engineering and medicine, on a site with "News for nerds, stuff that matters" as the tagline would be a bit more substantial.
To say it's worthwhile to teach kids about old technology is to presuppose that they'll even benefit from such effort in any way (preferably at least somewhat proportionate to the amount of time they're made to invest) but if your kid wants to become a dancer, a musician, a novelist, a racing driver, a sculptor, a composer, etc. etc. there are far better ways to allow them to explore their own creativity than forcing them to sit in front of a bench with wires and batteries.
Had the author of this article (paragraph) put any effort into procuring supporting details beyond "I think" I might have felt differently. But given the laziness with which the subject was approached, I find little reason to regard this question as anything more than a waste of time.
