    TLDR

    AI's massive energy demands are driving major tech companies back to nuclear power for reliable baseload electricity. The deal underscores infrastructure bottlenecks in the "compute race," long-term bets on scaling AI infrastructure, and efforts to meet sustainability goals while supporting data center expansion for AI workloads.

    @zeng_xian40157AI is having a wild day: 1) Tavus' Griffin passes the video Turing test — 48% thought it was human 2) Amazon signs a 20-yr nuclear deal to power AI data centers 3) AI now = 40% of the S&P 500, 87% of VC funding The compute race is the real story. #AI #MachineLearning #Tech
    @nicosokufxAI半導体「次は“光メモリ”が主役に?」電線・NTTなど!?🤔 あまり日本では話題になっていないが 米サンフランシスコの半導体スタートアップ Volantisが約138億円を調達。 ✅AIの「メモリの壁」を光で突破 ✅GPU⇔メモリを光インターコネクトで接続 ✅220個超のメモリチップを巨大プール化 ✅A-1は20兆パラメータ超・最大1万token/sを目標 👉ポイントは 「GPUを速くする」のではなく、 “メモリとの通信”を速くする発想⭐️ AI半導体競争は GPU → HBM → 光インターコネクトへ? ⚠️まだ設計目標段階。顧客向け出荷は2027年予定 ↓ 今回のニュースから日本株へ連想するなら、 古河電工・住友電工・NTTあたりは 「AIの次のボトルネック=電気配線を光にする」という中・長期的なテーマ
