Scaling up these neuron cultures is rather something like "head cheese" from Greg Egan's "Rifters" novels (artificial "brains" trained to do network filtering, anti-malware combat etc.).

> To conduct the CT scans, the large mass was evaluated by a third-party laboratory under NTSB supervision. This facility had a range of scanners with different power and energy levels and could scan large masses using a rotating table, avoiding the need to rotate the mass itself. Ultimately, the third-party laboratory attempted to image the large mass at a power as high as 320 kilovolts (kV). The scans conducted at 320 kV were not powerful enough to penetrate the object, and as a result, no internal structures or voids were visible, and no memory devices could be identified. The NTSB evaluated using another laboratory with higher power and energy CT scan devices, however, there was concern that increased CT scan energy could damage data stored on any surviving NVM chips. Consequently, higher-energy scans were not pursued.

I'm no expert, but remember reading about neutron imaging ([1]). I'm curious if that was deemed unfeasible, too expensive, or having little chance of success? From Wikipedia:

> X-rays are attenuated based on a material's density. Denser materials will stop more X-rays. With neutrons, a material's likelihood of attenuation of neutrons is not related to its density. Some light materials such as boron will absorb neutrons while hydrogen will generally scatter neutrons, and many commonly used metals allow most neutrons to pass through them.

Surely it will be possible to also store it on some government-issued, GCHQ-vetted digital device, and not rely on foreign companies (Google/Apple) and their locked-down mobile platforms?
