If you are building a product, my advice is to take the same time you would have taken before AI.
The reason is AI has lowered the barrier to entry. If you build an app in a few days, you’ll now be competing with tons of similar apps, including vibe-coded ones.
You need to go to the next level. It doesn’t mean adding more features or making the app complicated. Use the time to polish it, focus on user experience, spend time on marketing, and anything that differentiates it from others.
