A blacksmith was a person that picked up chunks of carbon and heated them to they were glowing red and beat the iron to submission with a hammer in their hands. Today iron is produced by machines in factories by the mega-tonne. We just happened to live in the age where code when from being beaten by hand to a mass produced product. And so the change of technology goes.
And the blacksmiths losing their jobs are not allowed to feel bad about it?
Think of the wonderful world we could have if everyone just got their shit together and became paper trillionaire technocrats.
