I enjoyed reading your summary. From a scientific point of view, the last 5 years have been amazing for brain-computer interface technologies. I agree with your assessment:
1. That melding human brains with computers is inevitable, 2. That it feels far-off but is likely closer than we expect, and 3. That people simultaneously felt some enthusiasm for it but a deep sense of unease.
Recently I tried to explain the science and scientific ideas behind brain-computer interfaces; feel free to check it out if you are interested. Should be right up your alley.
All the best!
