That's interesting. As a ST fan, I always thought Roddenberry's vision of the future was compelling. We have visionaries in the tech world today that look out 5 to 10 years, but very few who are reaching out 100 years from now.
On the tech, I think the biggest restriction will always be the bandwidth. Even if every system is parsed down to the smallest distributed elements, there will always be the problem of delivering the results somewhere. Reading the part about 80,000 views of an individual athlete from fan cameras just makes me wonder how we might provide an infrastructure that doesn't come to a grinding halt in that scenario, like it does now when 30,000 people in a stadium trying sharing a photo on Facebook.
