This is the kind of sensationalist nonsense.
Neurons are not as efficient as silicon in terms of computation. The power parameters reported here are the power requirements for running an incubator and 4% CO2. This is the cost of life support as available in the any standard cell culture in thousands of biology labs all over the world. The energy for computation comes from glucose provided in cell culture medium to the cells, which is more energetically much more expensive than electricity. Cells have a maximal efficiency of about 40% in extracting this.
Also, neurons will die in culture. They will also change in culture. They have to be replaced periodically and the underlying silicon will have to be retrained again for performing computations.
