Recently, Twitter's timeline has been almost filled with various AI products and free open-source tools. Although I don't understand technology at all, seeing some aesthetically pleasing open-source tools makes me want to deploy and experience them myself. In the impact of this "threshold collapse," I have two deep feelings: 1️⃣ SaaS is being diminished by Agents: When there's no longer a need for someone to "operate software," the complex business processes and UI moats of SaaS instantly crumble, leaving possibly just an Excel sheet. 2️⃣ Vibe Coding is not a technological revolution, but an aesthetic revolution: The coding threshold has disappeared, execution has become cheap, and product sense has become the only ticket to enter the AI era.
