The machines of Tatjana van Vark
How many on earth can build those instruments from scratch ?
Even one of those instruments ?
What percentage of the global population ?<p>I am wondering if we are building a civilization weakness, where only few can recreate those things.  As we produce at scale, and with more and more layers of automation, we need less and less craftsmen... and if those few at the top get hit by a bus, the setback could be huge.<p>Combined with technology that evolves faster than we can teach it, it feels like the number of experts is shrinking over time.  Thoughts ?
