We work on the Spanish-Portugese problem.

Both sought India through the 1400s. The Portugese (da Gama) brute-forced their way along the coast, essentially navigating by line-of-sight.

Kids hold the edge of the pool, or touch sand at the beach. Similarly, investors cling to line-of-sight in their ventures.

The horizon stretches 12 miles. After that, the curvature of the Earth occludes what's next. To sail inside that intellectual boundary, always within the comprehension of Lisbon, is infra-horizontal.

The Spanish (Columbus) rolled the dice and sailed west, beyond the horizon, breaking line-of-sight. This method, of boldly going where none have gone before, can be described as supra-horizontal.

In civilizational terms, the S/P dichotomy repeats itself in today's space exploration. You have da Gama, tiptoeing to Mars. And then you have Columbus, warping to outer space on post-Einsteinian physics.

Warp drive? Runs on DIY Lithium crystals.
