Just because the AI systems we have today aren’t what most people thought they would be, it doesn’t mean in a few years it’s not a whole different game.
This isn’t like we invented AI and it sucked so we declare it a waste of time. The AI of today is like those massive “mobile” phones we had 30 years ago with 15 minutes of battery life. It’s the first iteration of it. This is the worst it will ever be. In a decade or so it will be unrecognizeable compared to the AI systems we have then.
