When building an MVP took months, founders naturally spent more time discussing ideas, validating assumptions, and deciding what to build.

Today, AI can turn an idea into a working prototype in a weekend.

That sounds like progress, but I think it has quietly shifted where the real cost is.

Building is cheaper than ever. Making the wrong product decision isn't.

As someone who manages social media, I also have to manage what happens in the comments section.

Sometimes it's constructive criticism. Other times it's pure hate.

I've started to notice something about mature products.

The size of a feature rarely determines how much work it takes.

Instead, the effort depends on how many past decisions that feature touches.

A simple "Add Google Login" suddenly affects authentication, onboarding, permissions, analytics, documentation, QA, and maybe even your pricing model. What looked like a two-hour task turns into a week of discussions because you're no longer building a feature; you're negotiating with decisions your product has accumulated over months or years.
