Bookmarks and data filtering are intermediate technologies that help make more technologies (they are necessary, but useless in and of themselves). When I say better tech, I mean:

- Less human effort and overall cost to construct net-new housing (and frankly "achieve safety").

- Less human effort and overall cost to grow and transport food.

- Less human effort and overall cost to clean and transport potable water.

- Less human effort and overall cost to keep everyone's bodies healthy.

- Less human effort and overall cost to keep everyone's minds healthy.

- Less human effort and overall cost to keep our planet healthy i.e. appropriately and continually terraformed for our needs.

- Less human effort and overall cost to travel/explore any and every inch of this planet (including the sea floor, the highest mountains, the sky, and even orbit). Fuck it, why think small, even less human effort and overall cost to travel/explore every inch of this universe.

These are the technologies we need to get more people outdoors!
