Product development when technology changes rapidly

I wanted to build a video editor into X like other social apps. I had expected it to take 3 months of engineering time. Today I decided to try prototyping it myself. I one-shotted a full in-browser editor in 15 minutes. It felt like I could replace the entire Adobe software suite by Sunday. Then I asked myself: will videos even be edited manually in 3 months? Chatbots can do reasonably well now. Product development is getting extraordinarily difficult when the world is changing so fast.
