A decade ago Bootstrap helped a generation of programmers who don't know how to design make pleasantly looking websites. I fail to see how Tailwind is better suited to that task than Bootstrap.
With bootstrap, there was a fixed set of components to pick from. For a lot of things, there were no suitable components, so people used those that they had for everything else, kind of like designing furniture in Minecraft with blocks. This makes bootstrap interfaces bland and overly similar, in a way that Tailwind doesn’t: its design system is fundamentally based around design tokens arranged in sensible steps, not full components. That allows for a lot more flexibility and stylistic control.
