A hacker was once a computer enthusiast, and the media made it into a name for criminals who break into other people's systems.
Decades ago, people started using baud when they meant BPS. Not many technical people back then, but it wasn't possible to correct the few who made the mistake. Even one top member of the CCC (Chaos Computer Club) said it's just “baud” now, no matter the real meaning.
(baud = symbols per second. A symbol can transport multiple bits, so a V.32 modem with 9600 bps worked at 2400 baud, 4 bits per symbol.)
GIF is an image format. Multiple frames stored in such a file can get played like a video. But today every video without sound gets called a GIF.
AI is an old term. But today most people say AI but only mean genAI.
It's even more absurd: There are gamers who demand computer games without AI. WTF?
AI was always part of computer games. Even the early computerized board games. I remember Half-Life fans loving the enemy AI. And I think one of the games in the Wolfenstein franchise had enemies that found cover when shot at. That's normal, old AI. Not genAI.
If AI is really lost, how do we discuss the thing that was once considered AI?

"Lost?"
None of those terms have been lost. They've just come to have a wider definition than before. Language evolves over time as people are exposed to new ideas, words, or terms. As non-technical people begin using the terms, the meaning has an understood meaning to the public that most people use (e.g. AI/genAI), and a technical definition that is still understood by those it is relevant to. It just requires context.
Yes, words have meaning- but words also change over time as the public understanding shifts. Just like the word "literally." It used to mean something that is/should be interpreted exactly as it is said/written/shown. Now "literally" also means "figuratively," even within the dictionary.
So, no. It isn't lost, you just need to give context about what form of "AI" you are referring to.
