TikTok buyout could cost $100B – and won’t include the algorithm
A TikTok buyout by an American company appears to be the only way for the app to survive in the US, and potentially in Europe too. But potential buyers could find themselves paying a lot of money and not getting the one thing they really want: the al.....»»
Apple chipmaker TSMC makes contingency plans against Chinese invasion of Taiwan in 2027
The prospect of a Chinese invasion of Taiwan is a nightmare scenario that keeps western intelligence agencies awake at night, and there are growing concerns that this could happen in 2027. With the US legally obliged to defend Taiwan, the potentia.....»»
