I don't have the amount of time I used to to do that stuff either but the curiosity of it has never died and if I had more time I'd still do it.
If I ever lost that drive I think I'd rather be dead.
I say thus not to dampen your enthusiasm, but rather to encourage you to enjoy it to the maximum while it lasts.
Everything has a season and in that season it can seem terribly important. Perhaps an activity, or a favorite sports team, or a group of friends.
Some of that remains forever, some of it gets deferred as other things happen. It's part of life, we grow, we change, the world around us changes.
It's not that the drive is lost, it's just that it manifests in different ways, different activities, different challenges.
When you see a post like yours in 30 years time, remember this moment, and raise a glass :)
I wonder how many others had this exact same thought, before they lost their "hacker" drive while also preferring to continue living.
This may shock you, but people's interests and desires can evolve over time, even when those people don't expect them to evolve.
This is all good and natural, if it’s organic and not growing it’s probably not alive.
