I think the latter topic is generally more fun to commiserate about than the former. I have empathy for anyone that ernestly tries something ambitious and fails, and I'm glad the author found insight from the experience. Reading the article though, it sounds like the startup didn't really have a clear direction or momentum, tried to fix it by pivot ing to something technically "cool" without any business plan or realistic customer stories in mind, and then ultimately failed to create a sustainable business from that technology. A good lesson to learn from others rather than first hand, but not great subject matter to light heartedly banter about!
