It depends. For numerical simulations, you’ll want to generate true random numbers to check the robustness of your results. So using a CSPRNG/true random to obtain the seed is very useful. For debugging, you pick an injected seed to start with (+ print the production seed if a specific run had a problem and you want to debug). For cryptographic applications you want as secure a random seed into your CSPRNG as possible.
