Scientists have finally stopped playing pretend with robot dogs and brain-inspired algorithms. Instead, they’ve gone full mad-scientist and started gluing actual living frog cells together until the little blobs grow their own nervous systems and start swimming around like confused tadpoles with PhDs. Welcome to the era of neurobots — tiny biological machines that organize themselves, wire up neurons, and make you wonder if your future Roomba will file for emotional support.
