When it comes to the new AIs I think that, while caution and covering our asses as much as possible are a must, we should be careful not to jump at shadows of what-as-not-yet-come-to-pass. it's a judgement call that, no hard or fast rules to follow, but so much is.
As a semi-relevant comparison: My aunt and niece have a small business making soaps. These are hand made (as much as that can apply - some of the ingredients you really don't want on your skin), low volume of production. They cannot possibly compete with a fully automated, mass-production factory style set-up, or the mass distribution abilities of a large company. Hence, by the logic that suggests everyone who now has an AI as potential competition is just waiting for the axe to fall, their business should never have a chance. yet it is thriving.
Another example is the internet, and digital media itself: In principle, since the days of Encarta, anyone with access to a computer has been able to look up almost any piece of information. But it turns out that there's a difference between having a fact written down, and being able to understand it properly in context, and make use of it to solve a problem. Hence, schools and training programs have not become defunct, despite several decades of this technology becoming ever more widespread and capable.
True, those aren't perfect comparisons. And, true, the markets and interests involved will change, and some of us will fall afoul of those changes. But some will adapt, find new niches, and some may find ways to actually thrive off it. And, as with everything, we do not actually know how the markets and opportunities will play out until we actually see it happen. History shows that these things are very complex and unpredictable systems, and usually develop in ways that are at least somewhat unexpected, especially when given an unexpected shove.
So I would suggest being careful, watchful, flexible, and keeping an open mind as to where a given skill set of yours might find an application or demand - but it would be as much a mistake to assume that GPT means there's no longer any point trying to write your own material, as it would to assume that GPT and it's brethren can simply be ignored.- the list in the OP is as much one of potential opportunities as it is of potential threats. And the genie is out of the bottle, so we'd best look hard for ways to extract the former from it.
