Just because the API is bad doesn't mean we should throw money at it. I agree that NumPy might not be the best recipient either. It's hard telling, really. Personally, I believe the biggest blocker for me is to have good visualization tools. That's ultimately what gets me paid is showing other people my work and getting them to give me money to continue it. On the core science stack IMO there's numpy, scipy, sympy, matplotlib, pandas and xarray. I probably use it next to least, but I really think sympy is the one that could benefit the most from some funding.
