@jamesbond The difference is in the hardware. Better processors more connections and Quantum computers. Hardware switches that behave like neurons and synapses.
The biggest breakthroughs are not the thing called "AI" but it is the advances in abilities to translate brain signals and interact with them including generating responses. Those technologies have HUGELY advanced, and very few speak of it unless you are directly involved with the work or are a family member of the amputees and quadriplegics that are participating in the research programs.
They now can hook up a brain to a machine arm and the subject can move that prosthetic hand and arm like it was the limb he was born with. These advances also have led to the ability to successfully bypass damaged nerve connections and use a hardware solution to give motion to someone paralyzed in an accident from the neck down and most importantly can now return feeling and the sense of touch on the artificial hand and fingers that are directly processed by the human brain.
This "Bionic" advancement later matched to improved software that works on neural networks artificial and natural, will be the verge of a real potential problem once mankind is added to the mix. Once it all operates well enough it will be the base for new military weapons.
It all boils down to either it's use as weapon to kill and control or to make ridiculous sums of money as in profit. Last thing will be the medical advances that it all began with.
