2025年要结束了，马斯克吹过的牛，没有一个兑现

Group 1: Core Insights - Elon Musk's ambitious commitments for 2025, including advancements in autonomous driving and artificial intelligence, have largely failed to materialize, leading to a significant credibility crisis in the market regarding his future projections [1][2]. - Tesla's Robotaxi service, which was promised to cover half of the U.S. population by the end of 2025, is currently limited to a small area in Austin, Texas, and still requires human safety monitors, contrary to Musk's claims of achieving full autonomy [1][3]. Group 2: Financial Commitments and Government Spending - Musk's leadership of the government efficiency department (DOGE) has not resulted in the promised $2 trillion reduction in federal spending; instead, spending increased by approximately $248 billion in the first 11 months of 2025 compared to the previous year [1][4]. - The initial goal of reducing federal spending was revised down from $2 trillion to $1 trillion, and then to several hundred billion, indicating a significant failure to achieve the intended fiscal savings [4]. Group 3: Delays in Technological Advancements - The timeline for achieving artificial general intelligence (AGI) through Musk's company xAI has been postponed, with no significant milestones reached in 2025 as initially promised [2][5]. - The highly anticipated Tesla Roadster prototype, which was expected to be showcased by the end of 2025, has not been released, and the promised flying car demonstration has not occurred [5][6]. Group 4: Space Exploration Setbacks - Musk's long-term vision for SpaceX to send humans to Mars by 2025 has not been realized, with the goal remaining unachieved as of the end of 2025, echoing previous unfulfilled timelines [2][7].
