Chinese-Canadian history commentator Jiang Xueqin has drawn attention after alleging that bitcoin is not a grassroots technology but could be linked to U.S. military institutions. He called it “the biggest scam in existence” and said it was designed as an ultimate surveillance technology. Jiang cited Satoshi Nakamoto’s anonymity, past U.S. military research spin-offs, bitcoin’s public ledger and possible CIA use. Critics say the claims lack concrete evidence.

Technology is reshaping daily life, but a new phase is emerging in which people remain central as AI enters care, work and learning, Amazon CTO Werner Vogels writes. He points to evidence for companion robots easing loneliness, argues generative AI will elevate rather than replace developers, and warns quantum-era threats demand immediate adoption of post-quantum cryptography and talent development. Vogels also says defense innovations will move into civilian use faster and predicts AI tutoring will become ubiquitous.
