The reason behind your point is pretty simple too. Technology has never evolved to this much extent in the past and internet has never been used as much as it is at present. Millennial generation spends most hours of the day surfing internet. They are more comfortable with machines and computers as compare to their adults. This generation also wears the face of future bitcoiners.
The internet is around more than 20 years and not only millennial generation are experts in that, the older generation does outdoor activities too and not to glue in front of the computer all the time but the present generation is different and it will cause many health issues too, obesity in a major issue as they are not interested in outdoor activities nor working out and a healthy general is what we need rather than just nerds who can sit around the computer.
