Acharya Prashant explains that the continued use of animals in scientific research is primarily driven by economics rather than necessity or ethics. He argues that animal experimentation persists because it is cheap, especially when animals are sourced from developing countries. While proponents claim such research is essential for medical advancements like cancer cures, Acharya Prashant asserts that modern simulation technology and supercomputers are already capable of modeling complex systems, such as the entire universe or global climate patterns. The choice to use animals instead of advanced computer simulations is a financial one; developing sophisticated software is expensive, whereas animal lives are currently assigned no economic value.
