I don't think the problem is mechanics though, it's compute. A portable AI engine should constantly process a vast amount of data from different sources. Even if you wirelessly connect it to a supercomputer, network latency is going to make it useless. Remember Google Stadia? Basically you need a mobile supercomputer that is powered through air. And at that point, it's better to be able to defend itself because this shit is expensive.
