Georgescu states that current virtual cell models have limited effectiveness, saturating after processing only a small percentage of their input data, and that cells in lab settings often fail to exhibit significant changes when genes are knocked out, limiting the potential for extracting causal relationships. The claim is supported by a linked reference.
