Since that software was produced by handful of very smart people, that irrelevant to question of whether you can make a pencil without a boss telling you how to do it.
You can make some gun parts with a threedee printer and software downloaded from the internet, but some gun parts you cannot. And for a very long time, no one could make those parts except existing large scale gun makers.
And watching Ivan the Troll make those gun parts, it was absolutely obvious to me that come civil war II, it is not going to be a large number of people making full auto weapons in their home workshop. We are going to have to conscript Ivan the Troll, and conscript a thousand people to do what he damn well tells them to do.
There's a principle there I do agree with. The benevolent dictator, the individual with capacity - call it creative intuitive or inherent or something. I am well aware that those of capacity ("any relevant level of capacity" perhaps?) cannot be duplicated in general. And yes, come civil war, very few will have the ability and capacity to create anything particularly useful, in a relevant time frame, to the defence of their family. I think calling "inherent intuitive ability in one or more areas" "a boss" leads to unfortunate descent of the conversation. One of the great problems of today is the Marxist indoctrination of many, when they go to college, and combined with the relative technological abundance and access to Wikipedia we have, a lot of "spoilt brats" think not only can they do anything, but that the world owes them everything and they ought not have to lift a finger to receive everthing, and this approach has gottem them a fair way in the "cotton wool parents" world we now live in. And come civil war, a few inherent but long buried facts will, usefully if painfully, expose themselves rather rudely to those who've been living such delusions. Anyway, there are those who are intent on building up the publicly accessible knowledge base on how to make things. Some will join them. Perhaps even someone who already knows how to make pencils, and perhaps few people will even be able to follow the instructions - perhaps none (though I doubt that - such a view smacks of ego hubris); timeframes though... I can't stop wondering about the Werner von Braun and NASA USA rocket building history though ... I usually prefer to have the discussion on the list by the way. Regards, Zenaan

Reminders: - LMR - Longitudinal magnetic recording (magnetic domain grains laying along the disk) - PMR - Perpendicular magnetic recording (magnetic domains stood up vertically - this was the last great density increase before SMR) - TGMR - Tunnelling giant magnetorestricive - this is a head technology needed to achieve PMR NB: ALL drives on the market at the moment are PMR with TGMR heads. They all use the same platters and the same heads - there is only one manufacturer for each of those parts, despite there being three HDD makers - SMR - Shingled magnetic recording. (More formally Shingled Perpendicular Magnetic recording) - TDMR - "two dimensional magnetic recording" - this is a marketing term to say "zoned media" without coming out and saying it. You need zoning otherwise there aren't gaps between blocks of shingled tracks and you'd have to write a disk from one end to the other. Coming soon (maybe) - patterned media (platters) - this will start separating the magnetic grains from each other to reduce crosstalk and improve density a little - HAMR/MAMR: heat assisted recording - needed because smaller grains need higher coercivity and the heads can't put out a magnetic field necessary to flip the field in the grains without heating them up to nearly their curie point in order to reduce that coercivity The reason I say "maybe" is this: SSDs just killed HDD economics at all sizes Micron have just dropped the price of their 5210 ION 8TB SATA archival SSDs to $700 apiece - and their 5200 Nearline/5300 daily SSDs aren't much more expensive. Then there's the NVME ranges... They all have 5 year warranty, power loss protection and even the IONs are warrantied for _at least 0.2DWPD (4kB random writes) up to 0.9DWPD (large sequential fills) which fall nicely into 90% of both my home and enterprise requirements. ... ----------------- This is an interesting bit:

It appears that PMR and TGMR are sufficiently complex manufacturing, and the competition (and in this case, reducing economies of scale) becoming so low, that HDD manufacturers no longer have much competition between them.
