The Nanobots are a way to our future’s pleasure or not. In the future we could have nanobots introduced into our brains via capillaries. Can you imagine a world of virtual feelings replaced without the barriers between man and machine. Food pleasures without calories. Brain technology will impact food sensory experiences and addictions. Especially when we already know that addictions are 50% hereditary and that includes food addictions. No one knows the future, expect the future.
