This is closer to rent a transistor, and the main use case is to find out what its voltage curves are.

It is not a computer.

I did work on a version which used in vivo brains for actual computation. It worked but no one wanted to invest in building the matrix for rodents. With the benefit of hindsight I shouldn't have added the slide explaining ethical considerations: 'Container Labs in international waters help us manage regulatory risks'.
