My ears always perk up when I hear about some interesting technologies. For example, I'm fascinated by real-time facial action analysis, DNA digital data storage, nuclear phone batteries, SS7, brain-computer interfaces, power analysis, and so on. These technologies may not make the headlines as often as artificial intelligence, but I still think they are very interesting.

I'm curious to hear from you: What are some technologies that you find most exciting or intriguing? What is it about these technologies that captures your attention?

I'm looking forward to discovering some hidden gems.

Thanks for sharing your thoughts.
