Could you elaborate on what extra stuff you are working on that will be a value-add over standalone Cursor?
v0/lovable/a0 will replace drag-and-drop "no-code" tools for non-programmers who don't care about code and only decide what the product should do. The tool will likely also manage hosting, either directly or through service providers, to ensure a seamless e2e experience, automatically fix runtime issues etc.
The question remains, will there be a need for Cursor and programmers in the future at all.
But keep in mind any point where programmers are obsolete is also the point where any job that can be done from a computer is obsolete. Including WYSIWYGing an app.
