In the start-up space, Tailwind is to product UI as Bootstrap was (or still is) to marketing-focused landing pages. It almost serves as a litmus test as to whether you work in a start-up like environment or an enterprise environment.

If you are in a design or product function in a enterprise company in non-tech industry, you steer clear from Tailwind. But, I appreciate its usefulness for developer's who just don't want to learn CSS or have the time to prioritise building their own design system — that comes with maturity.

In any case, Tailwind trades one CSS problem for another and it just illustrates that web development is not different than any other kind of development — it's all about managing compromises in technology and approach, based on your needs and future plans.
