Single cell sequencing technology is analogous to taking many radios, and listing all the parts the radios contains. Then clustering radios by similarity in their part abundances.

Useful, but a parts list is still far from figuring out how a radio works.

Not just that. For example one can perturb cells and try to understand their dynamics: https://cordis.europa.eu/project/id/810296

Also, from purely observational studies it is possible to infer mechanistic models as I outlined above, e.g. using SAT.
