对比中美机器人部署现状,指出中国占全球54%份额。
我刚刚意识到波士顿动力(Boston Dynamics) CEO 表达了相同的观点: “机器人是下一个风口。美国未来250年的建设将由机器人完成”。 然而,目前中国占全球机器人部署量的54%以上。 - 呼吁建立互联网规模的物理世界数据库(有点像 https://t.co/naeTygRRuB)
英文原文
I just realized Boston Dynamics CEO shared the same sentiment: “Robotics is next. America’s next 250 years will be built by robots”. However, currently China accounts for 54%+ of all global robotics deployments. - calls for Internet scaleable database of physical world (kinda https://t.co/naeTygRRuB

摩根士丹利上调AI资本支出预期,认为AI板块抛售过度。
@mkfilko 例如,摩根士丹利也预计受 $META 公告影响,AI 资本支出(AI capex)预期将上调…… 因此,所有 AI 概念股(AI names)的抛售似乎有些过火了。 https://t.co/UTyz9a7KrM
英文原文
@mkfilko Morgan Stanley for example is expecting an upward revision on AI capex from the $META announcement too… So selloff on all AI names seems like a bit much. https://t.co/UTyz9a7KrM

富国银行认为Meta出售多余算力验证了AI需求强劲及新云服务商逻辑。
富国银行:$META 计划出售多余算力,这是关于底层需求和 AI 单位经济学的积极信号。 “尽管有此转变,我们不预计 Meta 的资本支出会缩减,或整体算力需求降低。” 关于新云服务商(Neoclouds):富国银行认为这验证了 https://t.co/ZUV3ZvOQuA

Wells Fargo: $META intent to sell excess compute is a positive signal around underlying demand and unit economics of AI. “Despite this shift, we don’t expect a pullback in Meta’s capex or that overall compute needs are lower” Regarding Neoclouds: WF thinks it validated the https://t.co/ZUV3ZvOQuA

OpenAI拟向美政府出让5%股份,或获政府隐性支持。
我觉得特朗普可能会喜欢这个想法: 据《金融时报》报道,OpenAI 讨论了向美国政府出让其公司 5% 的股份。 如果这演变成类似 $INTC 的情况,美国政府成为其未来 1 万亿美元以上资本支出/义务的软性后盾,将会很有趣。
英文原文
I feel like Trump is probably going to like this idea: OpenAI discussed giving the US gov a 5% stake in its company per FT. If this turns into an $INTC type situation, would be interesting if the US government becomes a soft backstop for their $1T+ in future capex/obligations. https://t.co/KQZUyd950N

反驳META削减资本支出论,指出算力紧缺致谷歌削减对Meta资源分配。
关于 $META 因“过度建设”而“削减资本支出”的虚假信息甚嚣尘上。 这取决于他们是否真的存在过剩产能。 而目前的情况恰恰相反: 像 $GOOGL 这样的超大规模云服务商(Hyperscalers)计算资源极度受限,以至于不得不削减对 Meta 的资源分配。
英文原文
There’s a lot of disinformation going around about $META “cutting capex” because they “overbuilt”. This is an “if” they have excess capacity. And it looks like the opposite right now: Hyperscalers like $GOOGL are so compute constrained that they had to cut allocations to Meta

市场注意力短,需提醒MLCC等供应链瓶颈依然存在。
@MartinShkreli 我认为它们(瓶颈)和以前一样,只是有些像存储(Memory)那样变得更糟了。然后你会看到像 MLCC 或 WF6 这样的新瓶颈最近冒出来。只是现在市场的注意力持续时间极短,他们需要被提醒一个瓶颈仍然是一个瓶颈。
英文原文
@MartinShkreli I think they’re still the same as they were before, with just some like memory getting worse. Then you have new ones pop up like MLCC or WF6 recently. Just attention span is extremely short with markets nowaday, and they need to get reminded that a bottleneck is still a

市场短视追逐热门,抛售远期瓶颈环节。
这个市场感觉就像一条患有ADHD的金鱼,注意力只有5秒,只在交易热门主题。难道市场现在只关心物理AI和能源?那些在2028年后成为瓶颈的存储和光子学却被抛售了?
英文原文
This market feels like an ADHD goldfish with a 5 second attention span, trading popular themes. It's like markets only care about physical AI and energy right now? And sold off memory and photonics that are bottlenecked past 2028?

Shunsin确认与TSM合作后暴跌,博主认为无实质利空。
@SidkMena 不知道,可能只是板块抛售。Shunsin 最近确认了与 $TSM 的直接共封装光学(COUPE) 合作伙伴关系。随后股价暴跌 15-20%。我认为除了 SemiAnalysis 反复唱空 Nvidia 生态系统外,没有其他实质性进展。
英文原文
@SidkMena Dunno, probably just sector selloff. Shunsin recebtly confirmed a direct $TSM COUPE partnership. Then proceeded to crash 15-20%. Don’t think there’s any material developments outside SemiAnalysis bearposting the Nvidia ecosystem over and over https://t.co/jxKIKup6F3

摩根士丹利上调人形机器人出货预测并预警测试设备涨价。
最近看到的一些有趣新闻: 1. 摩根士丹利(MS):将中国2026年人形机器人出货量预测从年初的1.4万和2.8万台上调至5万台。 2. 摩根士丹利(MS):探针卡(Probe cards)和测试插座(Test sockets)可能涨价(贵金属上涨+严重短缺)

SIVE募资扩产InP激光器,暗示代工产能分配及供应链扩张。
$SIVE 正在筹集约 6100 万美元(6 亿瑞典克朗)以扩大磷化铟(InP)激光器和光放大器的制造产能。 Sivers 采用轻晶圆厂(fab-lite)模式,因此这可能暗示正在为跨 Jabil 及其其他合作伙伴的连续波分布反馈(CW DFB)激光器增产寻找代工产能分配/扩产。 这也可能 https://t.co/8F1cMcCxfB
英文原文
$SIVE is raising ~$61M (600M SEK) to expand manufacturing capacity for InP lasers and optical amplifiers. Sivers operates as a fab-lite model so this is likely hinting at foundry allocation/scaling for CW DFB laser ramp across Jabil, and their other partners. It could also https://t.co/8F1cMcCxfB

探讨人形机器人量产可能催生机器人化妆品新产业链。
我好奇人形机器人是否会引发机器人化妆品领域的新瓶颈/新行业。比如皮肤瓶颈。或者像 Aespa KPOP 机器人改造服务。所以如果 $TSLA Optimus 生产数千万台人形机器人:谁来让它们看起来都很有吸引力?

OpenAI独占Cerebras算力致非超大规模客户等待无限期
机器学习 $RDDT 子版块有一个相当有趣的轶事性投诉。 关于 $CBRS + OpenAI: - 需要 1-2K tokens/秒,所以尝试使用 Cerebras。 - 声称 OpenAI 预留了所有产能,导致非超大规模云厂商的等待名单无限长。 - 陈述 https://t.co/ZXPPg7v5Ch
英文原文
There was a pretty funny anecdotal complaint from the Machine Learning $RDDT subreddit. On $CBRS + OpenAI: - Needs 1-2K tokens/sec so tries to use Cerebras. - Claims OpenAI reserved all capacity, making waitlist infinite for everyone else not a hyperscaler. - Stated https://t.co/ZXPPg7v5Ch

质疑美国AI巨头资本支出大幅下滑的可能性,并提及中国AI网络威胁论。
很难想象一个世界,其中美国AI超大规模云服务商(Hyperscaler)的资本支出(Capex)从$GOOGL到$META会出现大幅下降。 当像360这样的中国实体声称: 他们现在拥有一种“AI网络核武器”,可以黑客攻击西方公司和政府。 (周声称Mythos就像AI时代的网络... https://t.co/pBbhuAfJk3)

Hard to see a world where US AI hyperscaler capex drops dramatically from $GOOGL to $META. When China entities like 360 go and claim: They now have a "AI cyber nuclear weapon" that can hack Western companies and governments. (Zhou claimed Mythos was like an AI era cyber https://t.co/pBbhuAfJk3

POET 暗示激光器短缺将延续至 2029 年,加剧供应紧张。
关于 $POET 年度股东大会及光通信市场阅读的一些笔记: - “前三大激光器供应商占据 68% 的市场份额,且未来两年完全售罄” $LITE 首席执行官表示短缺将持续至 2028 年,因此 POET 隐含确认激光器短缺将延续至 2029 年。 - https://t.co/Lx8IHQ9fyK

谷歌因算力限制Meta,致Meta转向Neoclouds且Gemini被削弱。

看好宇树国内前景,但认为地缘风险阻碍其进入美国市场。
@chengchushow 我实际上对宇树科技(Unitree)在中国国内市场非常看好(bullish)。然而,我认为中国的人形机器人很难在美国市场取得太多渗透。特别是考虑到DJI事件,黑客可以窥探每个人的家,这展示了外国公司所面临的(风险/限制)。

机器人投资飙升,AI数据中心供应链与人形机器人存在交叉敞口。
机器人是下一个风口。 根据 PitchBook 3月数据(来源:a16z),交易数量和投资金额均呈飙升态势。 好消息是:相同的AI数据中心(AI DC)敞口通常也涉及人形机器人量产的交叉敞口。 例如DRAM/NAND与存储(用于人形推理/存储)的关系,或DFB激光器与 https://t.co/7BrzCd3cWD 的关系。

马斯克收购光网络初创Mesh,分析其光引擎自研及激光器外采供应链。
$SPCX / 埃隆·马斯克收购了 Mesh,一家光网络初创公司。 该公司正在研发 1.6T OSFP(可插拔)光模块。 看来他们拥有光引擎/封装方面的技术,但很可能从商业公司采购连续波分布反馈(CW DFB)激光器。 $SIVE 是对初创公司更友好的供应商之一 https://t.co/A1H7Bd6ZU4

$SPCX / Elon Musk acquires Mesh, an optical networking startup. Which is working on 1.6T OSFP (pluggable). It’s seems they own the optical engine/packaging side of things, but likely sources CW DFB lasers off merchant companies. $SIVE is one of the more startup friendly https://t.co/A1H7Bd6ZU4

承认DeepSeek的创新性,主张用银行级监管框架解决AI模型蒸馏问题。
不,DeepSeek实际上非常有创新性。所以我才说美国模型只需要做好就行。至于蒸馏,那是另一个可以通过银行级安全/认证加监管解决的问题,至少对前沿模型来说是这样。因为分享凭证(如Netflix账号)给那些代理网络虽然违反服务条款,但还不构成犯罪。应该像共享银行账户一样来处理。
英文原文
Nah DeepSeek is actually very innovative. That's why I'm saying US models just needs to get good. As for distillation that's another problem that can be solved with bank level security/onboarding + regulations, at least for the frontier models. Since it's against TOS but not a crime to share credentials like Netflix accounts yet to those proxy networks. Should be treated like sharing bank accounts.
