Ultimately (and sadly) yes. While I never habitually or intentionally attended meetings to just look busy, I did work on something I knew had a long shot of creating value for the business. I worked on 0-1 products that if the company was more disciplined would not (or should not) have attempted. I left both on my own accord seeing the writing on the wall.

You said you were at large companies, so this is a hard call to make. A lot of large companies work on lots of small products knowing they probably won't work, but one of them might, so it's still worth it to try. It's essentially the VC model.
