AI is lowering the barrier to building products, but also making it easier for people to create systems they don't fully understand, leading to polished but fragile apps, workflows, and experiences. Rather than replacing product and UX design, this shift may make those disciplines more important, since the real challenge is no longer shipping quickly but building products that are coherent, trustworthy, and genuinely useful. AI works best as a tool that amplifies existing expertise — helping with repetitive tasks, research synthesis, documentation, and workflows. Speed alone has never guaranteed success. Blindly using AI without understanding simply allows teams and individuals to fail faster.
