Unless I’m missing something this article is basically saying a failed startup that couldn’t find product market fit was acquired by a large company for its team and some of its tech.
Maybe I skimmed the article too quick, but this exact movie is one that has been playing for decades.
Edit: Side note, my personal opinion on AI is that companies with existing distribution and existing audiences will be the ones that succeed (e.g. Notion layering AI on top its widely used existing wiki platform). Succeeding by building pure tech with no pre-established audience will be very hard.
