I'm trained in other fields (geoscience, computer science), but cognitive science is fascinating. To think we can "reprogram" or "newly program" memories in human beings is startling and just goes to show how ambitious modern science and technology is getting. I realize such technologies can be turned to beneficial or nefarious purposes, but what stands out to me is just how fast our quantitative studies of the human brain are progressing and how many different applications we are investigating now. Programmable memories? Wow!
