I might be a bit too cynical about this topic, but it really should be obvious to anyone in the field that you're not on track to become a PI this way. If you want to pursue the academic career, you need to focus on that from the start of your PhD. And you really need to be on some position on a track towards full professor after one or at most two PostDocs. I'm quite confused by the timeline here, though. A PostDoc is usually something around 2 years, maybe 3. Four PostDocs in 23 years is unusual, and indicates positions that are closer to something like a staff scientists usually done by people with permanent positions.
