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.)
I was careful not to include names or places, and all this information is easily searchable starting from the author's username on HN or the website name.
So while I maintain that I made my comment in good faith, I hereby acknowledge that it is okay if it gets deleted, should HN moderators be requested to do so.
Update: I will contact the HN moderators myself, as I feel it is the right thing to do here.
I get that they are having second thoughts after it got so much attention, but it isn't like they had a diary entry accidentally blow up, they actively promoted its spread.
So while adding a disclaimer or some clarifying context would be a good response, yanking the content down after it has generated significant discussion is wonky and I think posting the archived link is entirely reasonable.
call it callous, but I don't have a lot of sympathy for what is the direct result of their own actions. You make a post on HN, people have a right to be curious about it
