"We're about 20 minutes away from the point where Clarke's law kicks in and technology becomes indistinguishable from magic."

| The surface of a planet. |
| He was the pilot and engineer, the only other Terrestrial on Mercury. When you dove this far down into the sun's monstrous gravitational well, you couldn't take a big crew along. |

This expression quickly became a favorite of veteran sf writers; Heinlein, Clarke and Niven used it within a few years. Here's Niven using it as the subject of a short story, At the Bottom of a Hole (1966):
"The hole." Garner knew enough Belters to have learned a little of their
slang.
"The very one. His first instinct must have been to change course.
Belters learn to avoid gravity wells. A man can get killed half a dozen
ways coming too close to a hole. A good autopilot will get him safely
around it, or program an in-and-out spin, or even land him at the bottom,
God forbid. But miners don't carry good autopilots. They carry cheap
autopilots, and they stay clear of holes."
"He must have been on course for Luna when we found him. Ceres was behind
him with the radar. Our ships were ahead of him, matching course at two
gee. His mining ship wouldn't throw more than point five gee, so
eventually they'd pull alongside him no matter what he did. Then he
noticed Mars was just ahead of him."

Then some unknown race had chanced upon the dreamers and decided to "help them out."
'Improving man by bringing him close to Nature, while they combine the sensations of coasting with the interest of seeing the country well...'
Um, how about that pension for the humans who serve as the models for robot behavior?
'...used as surrogates in intense dependency cases.'
'Across the ground something small and metallic came, flashing in the dull sunlight of midday.'
