Most of the cost of a software project is from ongoing maintenance. When we make it easy to write the first version and make maintenance harder, the total cost of the project goes up.

Projects like FastUI allow maintenance of a project with fewer skills, directly reducing the cost of maintenance: owning teams spend less time learning and maintaining their skills and there are fewer bugs due to engineers making mistakes because of low skill-level in a technology.

Also, projects like FastUI make the project's tech stack much simpler. Simplicity helps reliability, incident resolution, security, testing, adding features, removing dead code, refactoring, etc. Highly-productive teams apply these ideas and keep their systems as simple as possible. As tools like FastUI mature, they will become standard in healthy engineering orgs.
