> When authors could not answer questions about the technical parts, and sometimes even basic questions about the paper, it is difficult to see how they could have verified the paper's contents

If you cannot answer, you did not author the paper, meaning you are misrepresenting your contribution, and there is already a process for this. And this is actually a really good test for any field. Use AI as much as you want, but you need to be able to explain your work. Applies to SWE as well, you need to understadn what you built, at the code level and system level.
