What’s the actual difference? Is it just a fancy name for features we’ve been using
More or less, yes. AI is marketing grift tech companies have been trying to sell us for decades. It never ever works but they continue to try and shove it down our throats year after year. It has the potential to be extremely valuable in a lot of ways but in reality it falls short of what is needed in order to be valuable. We've seen this for decades with Siri and Google Assistant. I don't know why, the only people buying it seem to be other corporations, right before it very predictably fucks them and then they discontinue it. There's also tons of money to make by defrauding "investors" with farcical hype, taking their money, and never delivering anything practical.
OpenAI made some major strides with the likes of ChatGPT and Dall-E and really kicked this whole revolution off but it's already crashing and burning.
