Previous generations set society up in a way that today it's not really necessary to work super hard. That's what we have been striving for as a civilization since the beginning. Free time to spend with our families and friends.
Without religion, nationalism, war, status"ing", etc, people have woken up and realized that life IS meaningless. If you don't have to struggle to survive, many will lapse into a state of torpor because why not?
Look how many people quit their jobs to travel around in a van and rock climb? That's basically the same as the video game player, but so what?
I believe people should be using their time and abilities to take care of themselves and their families, experience love and joy, and to hopefully leave the world a better place (at least not a worse place). There is still a lot of work to do (cure cancer, explore space, clean up our planet, build homes for people, maintain what we have) and ideally people will be motivated to work on these problems, but to do so just so you can have more sex is ridiculous. In the future people won't be exploring the universe Star Trek style just so they can have a baller pad in Miami and bang "10s".
