Suryananda's points are important. In terms of yogic advancement, overall, the average person will digress because of the technology. A strong yogi won't be affected by it, but most of the students will get carried away with the technology and will lose out on spiritual practice. This is mainly because people feel powerful and enabled by the gadgets. I have seen this repeatedly where a student gets a pride feeling because of using the technology and that converts into less practice and less advancement. It is to be regretted but the technology is so attractive that it grabs the students even more so that sex or addictive substances. Too bad!
