The cat is out the bag (Ad) Almost 80,000 tech jobs vanished in the first three months of 2026. Meta cut 14,000 roles, Microsoft offered separation packages to 8,500 workers, and Oracle is reportedly eliminating up to 30,000 positions. Goldman Sachs estimates 12,400 Americans are being financially displaced every single day. Analyst Porter Stansberry says the real driver runs deeper than AI - and two Nobel Prize winners have issued the same warning. He calls it the Final Displacement, and he's releasing a full investigation with specific companies to buy and sell before the next wave hits.
