Taiwan Semiconductor Manufacturing Company
“TSMC built the world's most expensive moat — $75 billion in fabs that take a decade to replicate, EUV lithography machines that cost $200 million each and have a two-year waiting list, and the only 3nm process that actually works at scale. The beautiful irony is that AI's voracious appetite for compute makes TSMC not just irreplaceable but increasingly essential — they're the landlords in a gold rush where every prospector needs their shovels, and the shovels cost $50 billion to manufacture.”
