People in this thread should take into consideration that the author submitted the post to Hacker News themselves. This is a call for the general hacker public to read it, and ultimately it cannot be undone easily.

I do understand the basic level of curiosity from fellow HN readers -- I did look up the research team and the supervisors mentioned. They do claim a really large area of research interests:

* Verification and Validation

* Search-Based Software Engineering

* Autonomous Driving

* Cyber-Physical Systems

* Digital Twins

* Quantum Software Engineering

It all adds something to the picture. That being said, I would not form any conclusions from this besides "a PhD student faces a crisis" -- unfortunately, this happens often and diagnosing those is really, truly difficult. (I am an assistant professor for just a year now, and I have seen those crises second-hand.)
