If we're looking for the current pig being chased through the (global) village (and please excuse my crude translation of "die neuste Sau durchs Dorf treiben", a German phrase to point out the current big thing that's being made the Biggest Thing Ever and gets mixed in everywhere) - I'd say it's certainly AI.
Personally, I'm very, very torn on that topic. Yes, it can be a great help, and very useful in specific instances. But then there's so many not-so-good things about it.
For once, I look with a shudder on the immense amounts of energy that go into generating, running, and using AI. It's slowly approaching a whole percent of global energy consumption, at a time where we'd all profit from dialling down a bit and trying to reduce what we use, so that we can stay within sustainable limits.
Then, a lot of it is just... bad. It already starts with the high-handed decisions of the AI trainers to just use anything that is there to train their models, regardless of copyright. Books, images, music, you name it. I have had issues with piracy of the book I wrote together with Gillian Polack (The Middle Ages Unlocked), which did cost both of us a good chunk of potential royalties income. This AI training - it''s piracy on a whole new level.
Artists complain as they are getting pushed out of their jobs, understandably so. A lot of people seem to think that AI will solve all their problems in the future, and make things, and better plus quicker than people. We will not be able to turn back time and go without AI, so my personal opinion is that it's smart to keep an eye on the developments and not reject all of it in every case, across the bank (even if personally, I'm a little tempted to do that, and please don't ask me why). In some cases, I have used AI to assist me, and I have found that it can be very helpful in some very specific situations. Like when I have a text in a language that I don't really read fluently, and I get translation assistance. (Quality differs between models, and it's always necessary to stay alert to possible hallucinations and mis-translations.) Like when I have a small, very well-defined programming issue where the language and (best case) the problem are rather well-known and have been handled and solved on the Internet somewhere, in some obscure corner, before, and I can describe in detail and very exactly what I need to have done, but am not able to just write out the code. Basically, another translation/language problem with a large pool of knowledge accessible in general. Or when I have a large, multi-page website and I need to find one specific bit of information on it (the case was a search for a VAT number that was not in the imprint).
In these cases, it has served me really well to use AI. Regarding the translation, it's a really helpful tool for me that aids me a lot, and makes reading texts that I'd stumble on and spend a long while leafing through dictionaries (or typing words into online dictionaries) much quicker and much more painless. In other cases that were close to my successful use-cases, but not quite as specific and well-documented, well, I tried, and it tanked spectacularly. Which means that now I am very motivated to be very specific, and think hard about whether it is an AI-solvable problem, or probably not.
If I could wish for something, it would be people using AI like ChatGPT less for everything. You really don't need it to generate you a recipe for Butter Chicken, there's plenty of them on the web already, written by humans, just use one of those. You can just, well, use a search engine (preferably one with the search function turned off). And while I can somehow understand the temptation of having AI render a photo of you into an action figure, or a cartoon character, or whatever else... I'd wish people would not just use it so freely. It has a high hidden cost, and at some point, the price will have to be paid.
