It also comes down to risk tolerance. At the age of 60 and up people are more interested in wealth preservation rather than following the latest tech developments and potentially make a buck out of it. If you lose money at such an age, it's very likely lost for ever. In other words, the older generation is thinking through every step they set two or three times before they spend anything.

The younger generation on the other hand isn't as risk averase. For them it's quite easy to recoup losses if they give it a year or two. The consequences are negligible in this case, which can't be said about the older generation.
