Well, you guessed wrong.

Yes, it can be used in general purpose workloads, with varying degrees of success. But its main purpose is made abundantly clear:
Accelerate Python Functions
Numba translates Python functions to optimized machine code at runtime using the industry-standard LLVM compiler library. Numba-compiled __numerical algorithms__ in Python can approach the speeds of C or FORTRAN.

Except this is an announcement on their funding situation, so strengths and weaknesses are completely irrelevant, unless Numba has a particularly interesting funding model. (The funding model is government grants and corporate sponsorship, so, not particularly interesting.)
