Because the next email is going to be "we demoed the app to our CEO and he loved it and he wants it in production". I have never seen the team back down from their ideas.

And also, I have been in similar sounding scenarios multiple times. They talk big when everything is going smoothly and nothing is on the line. The day shit hits the fan, they will furiously message me on Teams and insist that I support them in finding out issues. So far it has been about mostly about shitty design choices. This is at whole new level. They want to vibe code an app which will be used to plan and guide company's direction for the next year.

prototypes/mvp's often become the production version
