The Men Spending $50,000 Just to Reserve a Tesla Roadster

Source: Wired

Level

Tesla's long-delayed second-generation Roadster generated fresh excitement in mid-October when Elon Musk demonstrated the car briefly becoming airborne using a compressed-air thrust system. The flight lasted only a few seconds, and recharging the system takes six to seven hours. Despite these limitations, some buyers immediately moved to secure their reservations, captivated by the spectacle. Alex Lawrence, who owns an electric vehicle dealership called EVAuto, watched the live demonstration and placed a second reservation on the spot.

The Roadster has had a notoriously turbulent path toward production. Tesla first unveiled the second-generation model as a surprise at a 2017 event and began accepting $50,000 deposits immediately, with an initial target delivery date of 2020. That timeline has shifted dramatically, with Tesla now projecting production to begin in 2028 and delivery dates remaining unclear. To put the opportunity cost in stark perspective, reservation holders who had invested that $50,000 in Tesla stock instead would now be sitting on nearly $1 million.

The Roadster lineup is divided into multiple tiers with vastly different price points. The base model requires a $50,000 reservation deposit and excludes the thruster system entirely. The mid-tier Thrust variant, which includes the compressed-air acceleration system, demands a $250,000 deposit. The top-tier Rocket model—featuring the full flight capability—is listed as invite-only. Musk himself has acknowledged that this version will not be street legal, and purchase prices across all variants are described as estimates, with no confirmed figures yet published.

Lawrence sees the Roadster primarily as a business asset. His EV dealership boasts a large and rapidly growing social media following, and the reservations were technically placed in the company's name. He plans to use the vehicles for marketing content and track demonstrations rather than daily transportation. He remains determined to acquire the flying Rocket variant in particular, viewing it as a powerful tool for generating online engagement and brand visibility, regardless of the considerable financial and regulatory uncertainties involved.

Travis Cook, a Utah-based tech founder and self-described car aficionado, upgraded his nearly decade-old base reservation to the Thrust tier because he genuinely wants to drive the car. Holding a dealer's license, Cook regularly buys and sells unusual vehicles, and he relishes the social reactions they attract. He acknowledges potential frustration if the final purchase price approaches half a million dollars, though he admits he would likely still proceed. His wife, who does not share his enthusiasm for rapid acceleration, will probably not join him for drives.

テスラの長らく遅延していた第2世代ロードスターは、イーロン・マスクが圧縮空気を使った推力システムによって車が一瞬浮上する様子を10月中旬に披露し、新たな注目を集めた。「飛行」はわずか数秒で、システムの充填には6〜7時間を要する。こうした制約にもかかわらず、実演を見た一部の購入希望者はすぐさま予約を確保しようと動いた。EVAutoのオーナー、アレックス・ローレンスはライブ配信でデモを見て、その場でもう1台分の予約を入れた。

ロードスターはこれまで波乱に富んだ開発の歴史を歩んできた。テスラは2017年のイベントで第2世代モデルをサプライズ発表し、即座に5万ドルのデポジット受付を開始。当初の納車目標は2020年だったが、スケジュールは大幅にずれ込み、現在は2028年の生産開始を見込んでいる。機会費用の観点から言えば、5万ドルをテスラ株に投じていた予約者は、現在約100万ドルの利益を手にしていた計算になる。

ロードスターのラインナップは価格帯の大きく異なる複数のグレードで構成されている。ベースモデルの予約金は5万ドルで、スラスターシステムは含まれない。中位グレードの「スラスト」は圧縮空気式加速システムを搭載し、25万ドルの預託金が必要だ。最上位の「ロケット」は完全な飛行機能を持つが招待制で、マスク自身も公道走行が不可能であることを認めている。全グレードの販売価格は現時点で「見積もり」に過ぎず、確定値は示されていない。

ローレンスはロードスターを主にビジネス資産として位置づけている。彼のEVディーラーシップは急成長するSNSフォロワーを抱えており、予約は個人ではなく会社名義で行われた。車両はマーケティングコンテンツの制作やサーキット走行に活用する計画で、特に飛行可能な「ロケット」の入手を強く望んでいる。財務面や法規制上の不確実性が大きいにもかかわらず、オンラインでの注目度向上に向けた強力な手段になると確信しているからだ。

ユタ州在住のテック系起業家トラビス・クックは、自称「クルマ通」として約10年前に行ったベースモデルの予約を「スラスト」グレードに格上げした。ディーラーライセンスを持つ彼は珍しい車を頻繁に売買し、注目を集める瞬間に強い喜びを感じている。最終価格が50万ドル近くになれば不満も覚えるだろうが、それでも購入に踏み切るだろうと認める。急加速が苦手な妻は、おそらくロードスターへの同乗を望まないだろう。

Google launches Gemini 4 Carbon with a 'significant leap' in cybersecurity

Source: The Verge

Level

Google has released Gemini 4 Carbon, its latest frontier AI model, positioning it as a major step forward in coding, agentic task completion, and cybersecurity defense. The announcement highlights Carbon's top ranking on the Artificial Analysis Intelligence Index (v5.0), where it outperforms leading rivals including Claude Opus 5.5 from Anthropic and GPT-6 Astra from OpenAI. The model builds on Gemini 4 Argon, which Google released earlier the same month, and represents the company's most capable model to date.

Gemini 4 Carbon is initially being rolled out exclusively to a select group of cybersecurity defense companies, with plans to expand access through Google's Fairwind Program over time. Google describes Carbon as reflecting the rapid pace at which it is advancing AI capabilities. The company says the model delivers a significant leap in cyberdefense performance, making it substantially more effective at identifying software vulnerabilities and producing secure code compared to its predecessor.

Carbon currently holds the top position on two specialized security benchmarks. The first, SEC-bench Pro, measures an AI model's ability to detect real-world software bugs. The second, ExploitGym, evaluates how effectively a model can transform an identified vulnerability into a functional exploit. These rankings signal that Google is targeting professional security researchers and enterprise-level cybersecurity teams as primary users, rather than positioning Carbon as a general-purpose consumer tool.

One of Carbon's notable design goals is its capability to sustain long, complex tasks without abandoning them prematurely. Google reports that its internal teams have seen the model run continuously for days, persisting through dead ends to complete demanding multi-step engineering challenges. The model is also engineered to avoid taking shortcuts, resist prompt injection attacks—a common method of manipulating AI systems—and collaborate more effectively with users throughout extended workflows.

Carbon also aims to be more transparent and honest in its outputs. Google claims it reduces unsupported claims by a factor of two compared to Argon, helping users rely more confidently on the information it provides. Despite its advanced capabilities, Carbon launches at the same introductory pricing as Argon: $2 per million input tokens and $10 per million output tokens. This competitive pricing suggests Google is aggressively pursuing market share in the rapidly evolving frontier AI landscape.

グーグルは最新の最先端AIモデル「Gemini 4 Carbon」をリリースした。コーディング、自律タスク処理、サイバーセキュリティ防御における大きな飛躍として位置づけられている。人工分析インテリジェンスインデックス(v5.0)でトップを獲得し、アンソロピックの「Claude Opus 5.5」やOpenAIの「GPT-6 Astra」を上回った。同モデルは同月初めに公開された「Gemini 4 Argon」の後継にあたり、グーグル史上最高水準の性能を誇る。

Gemini 4 Carbonは当初、厳選されたサイバーセキュリティ企業への限定提供からスタートし、今後は「フェアウィンドプログラム」を通じてアクセス範囲を拡大していく予定だ。グーグルはCarbonを、AI能力の急速な進化を体現するモデルと説明。前身モデルと比較して、ソフトウェアの脆弱性検出と安全なコード生成において大幅な向上を実現したとしている。

Carbonは現在、二つの専門的なセキュリティベンチマークで首位に立っている。一つ目はSEC-bench Proで、実際のソフトウェアバグを発見する能力を測定する。二つ目のExploitGymは、特定した脆弱性をエクスプロイトに変換する能力を評価する。これらの順位は、グーグルがCarbonの主なユーザーとして、一般消費者ではなくプロのセキュリティ研究者や企業のサイバーセキュリティチームを想定していることを示している。

Carbonの重要な設計目標の一つは、複雑な長期タスクを途中で放棄することなく継続できる能力だ。グーグルの社内チームでは、モデルが行き詰まりを乗り越えながら数日間にわたって稼働し、複雑な多段階のエンジニアリング課題を完遂する事例が報告されている。また、近道を回避し、プロンプトインジェクション攻撃への耐性を高め、長期的な作業フローにおいてユーザーとより効果的に連携するよう設計されている。

CarbonはAIの出力の透明性と誠実さの向上も目指しており、前身のArgonと比べて根拠のない主張を半減させるとグーグルは主張する。高度な能力を持ちながらも、価格はArgonと同水準の入力トークン100万件当たり2ドル、出力100万件当たり10ドルに設定された。この競争力ある価格設定は、急速に進化するフロンティアAI市場でグーグルが積極的にシェア獲得を狙っていることを示唆している。
