Thank you to everyone who watches, comments, shares… and supports the channel 🙏 Right now, all around the world, governments and billionaires are spending trillions of dollars on megaprojects that were supposed to change civilisation. A city in the Saudi desert built for 9 million people. A Japanese train that floats on magnets. A $500 billion AI bet that's already falling apart. A nuclear plant that's cost nearly triple its original price and still isn't open. In this video, Beyond The Build goes deep on the 10 most controversial megaprojects under construction in 2026 — the real numbers, the real drama, and why almost every single one of them is a story about the gap between what humans promise and what humans can actually deliver. ⏱ CHAPTERS — see below 🔔 Subscribe for weekly deep-dives into the projects, technologies, and decisions shaping the world 💛 Support the channel: buymeacoffee.com/beyondyt1 📌 PROJECTS COVERED IN THIS VIDEO: 00:00 Introduction — The world's most expensive promises 01:14 #10 Hinkley Point C, UK — £48 billion and still not open 04:18 #9 HS2 — Britain's £100 billion train to nowhere 07:23 #8 Nusantara — Indonesia's new capital in the jungle 10:09 #7 Lower Thames Crossing — 16 years just to plan it 12:18 #6 Japan's Maglev — the fastest train ever built (maybe) 14:46 #5 Grand Inga Dam — the dam that could light up Africa 16:55 #4 Egypt's New Capital — a city for millions, with no one in it 19:23 #3 Project Stargate — $500 billion AI bet already fracturing 21:50 #2 California High-Speed Rail — 700% over budget, zero passengers 24:36 #1 NEOM & The Line — the trillion-dollar city becoming a server farm 27:22 Why do megaprojects keep failing? 28:55 Outro — What's coming next —— 🔍 SOURCES & FURTHER READING: All key facts in this video are sourced and verified.
