Because "unused muscle atrophy" applies very much to our technology as well. A lot of knowledge surrounding technological processes isn't really captured beyond institutional culture and individual memory. So if there isn't demand for some specific technology, the capacity and knowledge to build it will wither and die with the organizations and people who built it.

We can't do a Saturn V today. We might be able to do a Saturn V equivalent, though, as both NASA and SpaceX are retracing the steps towards heavy lifters.

This. And if one still struggles to understand the importance of institutional culture + individual memory, I would like into invite you to the following thought experiment.

“Imagine waking up the next morning and the world totally forgot all knowledge on Linux Kernel, and you are now tasked to release the next major version with major changes / improvements”

And remember the documentation and tests we have on Saturn V is certainly not as great as what we have on Linux kernel.

I remember reading that some of the textile techonology that enabled the arctic/anarctic expeditions in the early 20th century has already been lost.

They're having to analyse the garments in medical scanners to work out how the fabrics work.

The idea that technology that enabled the equivalent of the space race could be lost within a century is quite sobering.

You should write all this up on a single place, it's very interesting.

I just might put it up on my blog. Need to collect references for the things I've been saying first.

I first need to finish and ask someone to proofread my long overdue post on my views about advertising industry.

http://jacek.zlydach.pl, yes? I eagerly await this piece. I can think of a lot of people (and groups) who would find it enlightening!

Yes. I see you have an e-mail address in your profile; I'll drop you an e-mail when I'm done with it.

Hey person, I hope it wouldn't be to presumptuous for me to also ask for an email about this? I'd be very interested in what all you have to say.

Not at all! But since you don't have your e-mail published in your profile, you need to mail me so I know where to send the notification :).

Thanks. Already subscribed to your feed :)

I can proofread if you want.

Thanks. I'll send you a draft later tonight.
