It's worse. Vague requirements still only power vague interpretations of the problem. Even if you provide good requirements, you still only have vague interpretations at your fingertips. The promise is that such things won't be a problem in the future, which is obviously not materialising.

"Make a facebook clone" is the vague human promise to the end user. The reality is that it leads to so many assumptions which are insurmountable due to the vague interpretation so you have to change your requirements in the end to claim success.

Thus everything turns into a mediocre compromise. There is no exceptional outcome, which is what makes a marketable product. There are just corpses everywhere.

You need something better to both define requirements and implement them than this technology.
