I think you misunderstood the article - it's great to try new things, and it's not a problem to promise things you are not 100% sure about. What's important is the honesty - "I've tried, I've failed, here is what I learned". OP said the the best:
> "Failure" does not have to be a failure, and V itself does not have to be the sole product of V's development. Alex has time and time again promised to write blog articles on various aspects of V's development. Had he done that, instead of silently backpedalling on claims about V, we could have had very interesting reads reflecting on the challenges of creating a new programming language.
instead, we have disappearing claims that require internet archive to find out, denial of any problems, and blaming of every problem on "misinformation from haters".
You don't need to be corporate or in in academia for basic integrity.
