提到计算器这个东西，估计大家对它的印象应该是两极分化的，一部分人会觉得它只是手机里的一个功能而已，用来做一些简单的加减法，看看吃饭花了 多少钱等等。 而计算器对于另一部分人来说，直到快要 2026 年了，这个看上去有点过时的电子设备，仍然是生活学习工作中的刚需工具，甚至可以说是伙伴。 尤其是托尼最近找选题的时候看到了一个非常惊人的报道，说这个有着密密麻麻按钮的卡西欧计算器，现在一年还能卖 3900 万台。。。 不是哥们儿，这数字是个啥概念呢，就 2024 年全球手机出货量冠军 iPhone 15 ，一整年 "也就" 卖了 3660 万台。。。 托尼搜了一下，国外也有不少媒体引用了这篇源自法新社的报道，这个数字确实让很多人意想不到。 可是这也引起了很多人看到这篇报道的最大疑问：为啥都快 6202 年了，看上去过时的计算器还是这么坚挺？ 造成这个现象的原因有很多，不过与其这么问，倒不如说，计算器其实从来就没有离开过我们，它甚至还早就形成了一个探究极致的亚文化圈子。 在上世纪八九十年代，随着计算器越来越普及，它不仅是大人工作生活的工具，也陆续开始走进教育行业，成为了小孩哥们需要学习的一项技能。 其中法国和北美在这方 ...

Core Viewpoint - Texas Instruments (TI) is making a significant $60 billion investment in semiconductor manufacturing in the U.S., indicating a strong commitment to domestic chip production amid geopolitical tensions and tariff uncertainties [2][3]. Group 1: Investment and Expansion - TI announced a $60 billion project to build multiple wafer fabs in Texas and Utah, aiming to increase production capacity fivefold [4][5]. - The new facilities will support major clients like Nvidia, Ford, Medtronic, and SpaceX, with the Sherman, Texas plant expected to be operational by the end of 2025 [2][4]. Group 2: Market Position and Challenges - Despite the investment, TI's stock fell 13% following weak earnings expectations and tariff concerns, highlighting market volatility and uncertainty [3]. - TI's market share in the analog segment has declined from 19.8% in 2020 to a projected 14.7% in 2024, raising questions about the sustainability of demand [3][5]. Group 3: Technological and Operational Advantages - TI's chips are produced using traditional nodes (45 to 130 nm), which are less expensive compared to advanced 2 nm and 3 nm chips produced by competitors like TSMC [5]. - The shift to 300 mm wafers is expected to significantly reduce costs, allowing TI to produce 2.3 times more chips per wafer compared to 200 mm wafers [6][10]. Group 4: Environmental and Resource Considerations - The Sherman facility will utilize approximately 1,700 gallons of water per minute, with plans to recycle at least 50% of it, addressing environmental concerns related to water usage [10]. - TI's new plant will operate entirely on renewable energy, enhancing energy efficiency in chip production [10][11]. Group 5: Workforce and Economic Impact - The $60 billion project is projected to create 60,000 jobs in the U.S., although specific timelines for completion remain uncertain [11]. - TI has partnered with universities and community colleges to address the talent shortage in semiconductor manufacturing, reflecting a proactive approach to workforce development [11].
