High speed is a big thing. And actually high speed, at that. A massive number of trains are very slow and even a number of "high speed" trains are not even remotely as high speed as they could be, with proper investment. It's hard to replace planes when we're talking at least twice the travel time.
I'd love to have more train options in Canada. There is a train that spans the width of Canada, but it is so slow and deprioritized that it's not actually a viable means of transit across Canada. You can fly Toronto to Vancouver in a little over 4 hours. So maybe 6 hours with the airport overhead. By train, it's 4 days. That's something you'd only do for the experience and it'd be a significant part of the trip (one person I know who did it said that they wish they utilized more stops along the way, because by the end of the trip, they were getting pretty sick of it -- despite the fact that they recommended it glowingly). With a high speed rail, that could become less than 1 day trip, making it a lot more feasible (a lot of people already view the day they fly as a day spent only on travel).
And that's an extreme. Getting around southern Ontario is far more common and practical (it's an extremely population dense area). But the trains we have for that are very low speed and have mediocre schedules (sometimes only good for commuting). Even though a train is an option, I often find that the bus is actually the fastest way to get to my destination, cause the train is so infrequent and really not fast.
I only guessed a single one as generated by AI and I was wrong on that (the mouse in the boat drawing felt like unusual shaping and shading for a human). I really could not identify any telltale signs of AI in any of them, so answered entirely honestly that none of the others looked like AI generated.
To be honest, I expected that. The telltale signs people often talk about are only problems for bad AI art. Well done AI art really is indistinguishable. Stuff like weird fingers, faces, and teeth are only problems if the prompter is lazy and just picks the first thing generated (and doesn't selectively regenerate). If you're selective, you can get AI art without the things some people claim make AI art easy to recognize.
It's like photoshop or movie CGI. Anyone can detect a bad photoshop and we're used to seeing those. But well done photoshops by experts can be near impossible to detect (short of careful pixel level inspection, which doesn't really apply to AI art). Yet, a lot of people are over confident in how well they can spot photoshops.
I wonder if this will change anyone's mind? I've always wanted to do this for a few topics, including AI. I've also wanted to do this for trans vs cis people (so many transphobes claim they can "always tell"), movie CGI vs practical effects (see also: Captain Disillusion videos), and for various kinds of food and drink (so many people are elitist that something tastes better -- simple example that I've actually seen disproven is the various kinds of eggs, including store bought vs locally sourced).
