Wow, sure it's not at "super human" immune system levels yet, but this is the type of research that feels like we're entering SciFi territory.
I got used to it, and the feeling went away.
I had a similar feeling when I got a bluetooth headset where I just had to tap and speak and Google would answer almost any question I had, no need to even half shout "OKAY GOOGLE" for my phone to hear. I now actually feel dumber without such a headset because I can't easily get answers to random questions.
So, yeah, we get used to these things. The measure of "being in the future" is less the awe we have at technological marvels and more the way they become common place and accepted.
I take your point, but what's sci-fi is always a receding horizon :)
