In regards to AI and anything...
It hasn't given me much angst except in regards to cheating, creating another opportunity to exploit a lack of true human creativity, general laziness and how it will effect the music industry (which I dabble in), that is already a joke because of other technology.
However I can see AI as being beneficial to fly fishing in things like designing rod tapers. For example, I own more than a few custom rods in bamboo & fiberglass. I spent a lot of time discussing what kind of action I was after with the makers. For the most part things turned out well however often times additional "figuring things out" is required.
With AI it should be possible to plug in the data related to the action I wanted, maybe even factoring in the specs of the fly line I planned to use taking "trial & error" out of the equation and eliminate "dialing in" a rod by trying or purchasing 5 different $75 fly lines...
Even though I never read "shootouts" because I honestly don't give a rat's a$$, I'd LOVE if if AI took over that task taking the bias & subjectivity out of the whole process...
I'd be all for that!!
I'm sure there are many other applications in the manufacturing arena that will benefit as well like tippet & fishing line, hooks, waders, etc.
As far as AI being a tool to write the next great fishing book or to tell me where to go fishing, what to use and whether light color fly lines spook more fish than a dark color...
...color me NOT interested.
