How do you avoid pivoting every time a new tech hits?

It feels as if every six months the tech world changes its focus driven by a new tech trend. A years ago every startup tried to figure out how to add blockchain or Web3 to their roadmap. Today if your product does not have an "AI Agent or an LLM wrapper, investors and users ask why.
It is very tempting to pause your core product development just to chase the tech trend hype and gain a quick marketing lift. I have also seen products become confusing and bloated because they keep AI in places where a simple algorithm would have worked better.
How do you stay disciplined. Focused on your original vision? Do you actively ignore industry hype. Do you set aside a small portion of your time to test new tech trends just in case they truly benefit your users?
