Right. Currently in order to do state-of-the-art AI, you need a lot of _computers_ and a lot of _data_. Neither of these is easy to obtain by an individual in a basement.
We would need to consider, however, access to finished products (like trained models). In some cases in the future, having access to the appropriate model might be as dangerous as handing someone a nuke.
How hard would it be for someone to assemble a indiscriminate "killer drone," given the appropriate image recognition and flight control models?
