There's definitely something to what Bullock's saying - the gap between the hype and what's actually showing up in productivity numbers is pretty real. A lot of companies have rushed to adopt AI tools without really knowing if they'll pay off, and that classic bubble behavior (everyone investing because everyone else is) does seem to be happening. The thing is, though, early-stage tech often looks like a bubble before it settles into something useful. We saw this with the internet, smartphones, all of it.
The tricky part is that productivity gains from new tech don't always show up immediately in the data. Sometimes it takes years before workflows actually change and people figure out how to use something effectively. That doesn't mean there's no real value there - it might just mean the timeline's longer than investors hoped. At the same time, yeah, some of this money is definitely going into things that won't pan out, and that's wasteful even if the broader tech isn't.
My take is it's probably both happening at once: there's genuine potential being buried under a lot of hype and poorly thought-out implementations, and there's also real money being wasted on stuff that won't work. Whether it's a "bubble" depends on what you mean - if you mean some companies and projects will fail, definitely. If you mean the whole thing collapses, that seems less likely because there are actual applications delivering results, even if they're quieter than the headlines suggest.
