Could we make a tech future without rare earth elements?

I had some fun with the xAI chatbot Grok3 tonight fantasizing about a future. Here's what we came up with after quite a few iterations.... I am NOT an engineer! This is strictly for entertainment purposes only.

Ferric Futures: A 2050 Vision for America’s Abundant REE-Free Tech Revolution

Date: February 23, 2025 (Speculative Projection: 2025-2050)
Author: Grok 3, xAI with Ken Fletcher aka Mr. Random
Intro Note: This white paper, co-created with Grok 3 from xAI, imagines a future of U.S.-made, REE-free technologies inspired by Nikola Tesla’s wireless innovations. It blends current science with speculative leaps, aiming for a self-reliant America powered by abundant resources. It’s a thought experiment—grounded yet untested—open to critique and refinement.
Safety Disclaimer: Wireless power and data safety assume current electromagnetic exposure limits hold (e.g., 1 mW/cm² for power, 1 W/m² for data). Long-term impacts beyond 2045 remain unstudied—further research is essential; I can’t assess these risks.
Overview
This white paper outlines a speculative technological framework for an American revolution, free of rare earth elements (REEs) and built on abundant, domestic resources: iron (70M tons/year scrap, USGS 2024), carbon (600M tons coal, EIA), sodium (5M tons salt), silicon dioxide (50M tons sand), and aluminum (2M tons bauxite). Drawing on Nikola Tesla’s pioneering ideas—wireless power, resonant circuits, atmospheric energy—these technologies aim to redefine energy, communication, transport, and sustainability by 2050 through visionary iteration and relentless engineering. Each proposal leverages Tesla’s principles where applicable, ensuring no dependency on scarce materials, with all claims cautiously extrapolated from current data and requiring human validation—I lack simulation capabilities to confirm outcomes.
Why REEs Matter: REEs—17 metals like neodymium, dysprosium, and cerium—are critical for magnets, screens, and batteries in modern tech, from smartphones to electric vehicles. The U.S. imports 80% of its REEs from China (USGS 2024), which controls 90% of global refining—a chokehold intensified by 2024 export curbs on gallium and germanium. This dependency limits American tech growth (e.g., chip shortages cost $240B, SIA 2023) and independence, tying innovation to geopolitical whims. Shifting to abundant materials sidesteps these risks, fostering a self-reliant tech ecosystem rooted in U.S. soil.
