In this paper, I discuss arguments in favor and in disfavor of building for the Web. I look at three extraordinary examples of apps built for the Web, and analyze reasons their creators provided for doing so. In continuation, I look at the decline of interest in cross-platform app frameworks with the exception of Flutter, which leads me to the two research questions (i) "Why do people not fully bet on PWA" and (ii) "Why is Flutter so popular". My hypothesis for why developers don’t more frequently set on the Web is that in many cases they (or their non-technical reporting lines) don’t realize how powerful it has become. To counter that, I introduce a Web app and a browser extension that demonstrate the Web’s capabilities.
