So, using a program to do the job of an editor is one thing.
To enact the role of creator is of a different order.
However that is the trajectory. So, as two hundred years ago all glass was handmade & expensive and today most is mass produced with little human input, and bespoke pieces are appreciated more, so it is likely to become with written work.
Algorithms will produce adverts, copy, and churn out bog standard thrillers, romances, and the like which will be perfectly suitable for many occasions.
But there will be people who want to know a human wrote the thing.
I hope so, I'm working on my next write up about image generators. As a visual artist I am unsettled to say the least. Automation taking blue collar jobs is one thing but to steal a trade that is famously pleasurable to humans and part of the Follow your dreams category of jobs is another entirely!
Interesting. With a majority of people falling into the field of 'blue collar' whereby that means jobs which do not necessarily require extensive qualifications (although training & experience), then losing those jobs to automation is the bigger tragedy as it moves a huge amount of people out of employment which is essential for families, communities, and regions. See US rust belt, or UK coal towns.
It takes decades to recover, if recovery happens.
However. Yes, hopefully enough appreciators of the actual written word will remain in a way that cant happen with other industries.
