What counterarguments exist against the necessity of incorporating precise physics in text-to-3D generation

While there are numerous benefits to incorporating precise physics in text-to-3D generation as discussed above, some counterarguments exist against its necessity:

Complexity vs Simplicity: Critics may argue that adding detailed physics simulation capabilities increases the complexity of the generative process without providing significant practical value in all scenarios.

Computational Resources: Precise physics calculations require additional computational resources which may slow down the generative process or make it less accessible for users with limited computing power.

Overfitting: There is a concern that overly focusing on precise physics might lead to overfitting models to specific scenarios or constraints rather than promoting creativity or exploration in design processes.

Subjectivity: The interpretation of "precise" or "realistic" when it comes to incorporating physical laws into generative design is subjective; what one considers accurate another might find unnecessary detail.

These counterarguments highlight potential challenges related to balancing realism with efficiency when integrating precise physics into text-to-3D generation.
