はてなキーワード:Outlookとは
そういうことをChatGPTに聞くべきだと思い、聞いてみた。すると、
「石油が無くなるよりも、高価になって使われなくなる」方が先に起きる可能性が高いという。
自分がガソリン車に乗っているのも、ガソリンを燃やすのが好きなのではなく、便利で他の車種より安いからだ。これがEVが普及してスタンドも整備されたら乗り換えるかもしれない。
人類はかつて氷河期を乗り越えてきた。その後も様々な問題を乗り越え今に至る。
だとすると、石油やエネルギー問題もまた乗り越えるんだろうなと希望が持てる。
結論から言うと、「石油が100年以内に“完全に枯渇する”可能性はかなり低いですが、
“今のように安く豊富に使える状態が続く”とは限らない、というのが現在の科学的・経済的な見方です。
---
■ なぜ「完全枯渇」は起きにくいのか
● ① 採れる場所（可採埋蔵量）が常に増え続けてきた
技術が発達すると、
「昔は採れなかった場所や深さ」
→ その結果、埋蔵量はむしろ増えることがある現象が続いています。
---
● ② 「経済的に採れる石油」が変動する
---
● ③シェール革命などで供給源が増えた
2000年代以降、アメリカのシェールオイルが大量生産できるようになり、
“石油ピーク説（ピークオイル）”は大幅に後ろ倒しになりました。
---
■ では、100年後も今と同じように使えるのか？
これは NO になる可能性が高いです。
理由：
つまり、
■ 枯渇ではなく「高価になって使われなくなる」方が先に起きやすい
---
■科学者・エネルギー機関の予測のまとめ
予測者 /機関 結論 --- --- IEA（国際エネルギー機関） 「需要は2050年以降減るが、完全枯渇は見えない」 BP EnergyOutlook 「技術進歩により埋蔵量は長期的に維持される」 多くの地質学者 「採掘コスト上昇が先に来る“経済的枯渇”が本質」 →科学的・経済的には、
“100年以内の完全枯渇”はほぼ起きない
---
■もっと簡単にまとめると
—これはすでに世界中で議論されており、用途ごとに代替候補が違うのがポイントです。
用途別に、もっとも現実的な代替エネルギーを分かりやすくまとめます。
---
■ 1. 発電の代替
電気をつくる用途は石油依存がもともと小さく、代替が豊富です。
◎第一候補：再生可能エネルギー（太陽光・風力）
○ 補助候補：原子力（小型モジュール炉SMRなど）
- ベースロード電源として安定
△ 補助：地熱・水力・バイオマス
- 地域制約が大きいが、長期的には安定
---
■ 2.自動車（輸送）の代替
◎第一候補：電気自動車（EV）
○ 対抗：ハイブリッド（HEV）
△特定用途：水素（燃料電池）
---
■ 3. 船・航空の代替
◎第一候補：SAF（持続可能航空燃料）
○船舶は：LNG・メタノール・アンモニア
---
■ 4.化学製品（プラスチックなど）
◎第一候補：バイオプラスチック
○ 対抗：リサイクル技術の進化
△ 長期的には：CO₂から合成するプラスチック
---
■ 5.暖房・工場の熱源
◎第一候補：電化（ヒートポンプ）
○ 補助：水素・合成燃料（e-fuel）
---
■ 最終結論（用途別に一言で）
- 飛行機 → SAF
つまり、
◆石油の全用途を一つで代替できる“万能エネルギー”はない
◆用途ごとに最適な別エネルギーに置き換わっていく
■ 1. 「石油そのものが物理的に消える」未来ではない
多くの人が心配するような
→ 完全枯渇より先に「高くて使えない」状態になる
---
■ 2.不安の本質は「物理的枯渇」ではなく「エネルギー転換の過渡期」
実際のリスクは、
- 電気代が上がる
- 車の燃料が高くなる
- 社会インフラが変わる
といった、移行期間のコストと混乱の方です。
普通の生活者にとっては「徐々に切り替わっていく」感覚になりやすいです。
---
■ 3.世界はすでに“石油のない世界”の準備に入っている
- 再エネ（太陽光・風力）
- SAF（航空燃料）
への転換を前提に動いています。
---
■ 4.技術が進むほど、むしろエネルギーは豊富になる可能性が高い
エネルギーの「質」と「量」はむしろ増える可能性さえあります。
つまり、
● これからの不安は“消滅”ではなく“変化”の不安
● でも変化はすでに想定されていて、代替策も多数ある
という状況です。

WMとPRIが低めで衝動性が強いと、仕事で1番鬼門になるのなんでしょう？
そう！メールです。
タイピングの誤字に気づかない、TOとかCCとかBCCはなんですかそれ、ファイルの添付はすっとばす、いつか超重要そうなメールを違う人に送ったりして大事故を起こしそうで怖い。
今日も午前中に、「今君をCCに入れて送ったメールに添付してあるファイル、承認がおりたら○○に送っておいて」という指示を受けた。昼休みが終わって席に戻ってきてメールをチェックしていた時、その件のメールが目に入った瞬間「あ、これ経験的に転送するの忘れるやつだな」と思い、忘れないうちに即転送！（衝動性が高い）ちゃんと指示してきた人もCCにいれたぜ！完璧な仕事！とホクホク顔でいたら「なんでまだ承認降りてないのに送ってんの！？！？！？🤬🤬🤬🤬」（答え:WM低すぎて言われたことを覚えてないから）という事態が起きた。もうどうしようもない。もう今年30歳なのに……
というようなことをCHATGPTに話したところ、「Outlookでメール送る前にポップアップ出すマクロ書いてやろうか？」というエグい答えが返ってきた。
CHATGPTに発達やらかしを相談すると「こんな解決方法があるかも！」というのをたくさんくれる。世間のヤツらが言う「メモを取れ」「話をよく聞け」「集中しろ」「忘れるな」みたいな、それができれば苦労せんのだという低レベルな助言を遥かに超越した、発達特性をしっかり理解した的確な提案。もちろんVBA？のコード？も全部書いてくれる。
おかげで今僕のOutlookは、送信をクリックすると「送信前最終確認 送り先は？添付資料は？承認は得た？件名は？誤字脱字OK？」みたいなポップアップが出るようになった。
AIはこっちが作業に関してどれだけ質問しても嫌な顔ひとつせず答えてくれる。本当に1から丁寧に。開発タブが出てこない！と何度聞いたかもう分からない。
しかもAIが素晴らしいのは、こっちがどれだけ質問しても嫌な顔ひとつしない。それどころか、ミスって落ち込んでる人間のために丁寧に作業ができてすごい！ちゃんと対策して前に進もうとしててえらい！普通の人はなかなかできないよそんなこと！と作業がひとつ進む度に褒めまくり。普通の人こんなことをできないんじゃなくてやる必要が無いんだよ……🥲
ありがとうAI。あなたのおかげで僕はこれから、少しずつではあるけれど、まともな人間のふりができるようになるかもしれません。
あと、ありがとうストラテラ。あなたのおかげで、やっと「相談する」「対策する」という行動を実行できるようになりました。今まではやらかす→対策しようとする→対策しようとしていることが頭から消える→またやらかす→鬱になるみたいなことを繰り返していたので……

メールはあらゆるサービスに登録する拠点的なものになるわけだし
いつもと違うIPからだとメールに認証コードが飛ばされるみたいなサイトも多い
だからメールサービスにログインできることが重要になるんだけど、昔ながらのサービスはどんどん消えてる
フリメで国内での第一候補とも言えるヤフメは最近複アカしてるとアカウント削除されてメールが見えなくなるとかありえないことしてるし

Proxima Centauri b:
Thisis the closest exoplanet to us. Even thoughitsstar (Proxima Centauri)is ared dwarf that sometimes sendsout strongflares (which might harmlife),its closeness makesitone of ourmost interesting candidates. That’swhy we giveit a slightly higher guess (~2%).
Theseplanets are part of agroup orbiting a verycoolstar. Their environments might be challenging (for example, they could be tidally locked, meaningone sidealwaysfaces thestar), so the chance of acomplex, advancedcivilization might be abitlower.
LHS 1140 b:
Thisplanetis promising in some ways butis alittle fartherawayand around a dimmerstar, so our playful estimateis evenlower.
All of thesepercentages are extremely rough guessesbasedon whatlittle we understand about the conditions forlife andintelligence. Scientists useideaslike the Drake Equation to think about these chances—but until we have concreteevidence, thesenumbers remain just forfun and imagination.

In thesense ofbeing a strict mathematicalmodel with well-defined inputs and predictableoutputs, the Drake Equationis not accurate.Its accuracyis limitedbythe extreme uncertainties in several ofitskey parameters.

I'm thinking about the potential for non-human intelligentlife forms in theSol system and neighboringplanets, and how this mightfactor into the equation.
I'm thinking about how to integrate the emergence of non-human intelligentlife, possiblyonMars orEuropa, into the Drake Equation for theSol system and neighboringplanets.
It's interesting to think about the hypothesis of intelligentlife emergingonMars orVenus, thoughEarth remains theonly knownlife-supportingplanet in thesolar system.
Considering other realms
I'm examining if intelligentlife could have emergedonplanetslikeMars,Venus, orEuropa, and how thispossibility alignswith the predictions of the Drake Equation.
Hmm, I’m thinking about how non-human intelligentlifeonMars orVenus could intersectwith theassumptions of the Drake Equation, which seems tofocussolelyonEarth-basedevolution.
I’m piecingtogether the hypothesis of non-human, advanced, intelligentlife in thesolar system.Mars,Venus, and Titan present challenges, butEuropa and Enceladus might harbor microbiallife.
職場結婚で別部署ではあるが業務でも知らない仲ではない旦那に預けてみたら？たまには…とお偉いさんから直々に誘ってもらったもので、まるっと旦那に伝えてみれば、お偉いさんの名前が効いたのか当日は在宅してくれるってOKが出た。
出産以来初めての職場の飲み会だ。うれしい。（別に言うことじゃないが旦那はしょっちゅう飲み会に行ってる。付き添いや遊びや様々な）（そして私も日中に預けて遊びに行くことは何度かあった。平日の夜に行くのが初めてなのだ）
1か月以上前から言ってるから、忙しい旦那も調整できたのかもしれない。ありがとううれしい！
Outlookでわざわざ検索したら旦那のその日の予定が在宅になっていた。準備万端だ！
……とか言ってたら一週間前になって「当日って午前中は出社したらダメかな？」と言ってきた。いやなよかん。
「子供は日中保育園に行くんだから預けてる間は好きにすればいいんだけど、えっと、18時には必ず迎えに行けるようにしてね？」
会社はドアtoドアで2時間弱だから出社する時間がもったいない気がするが。
「さすがに18時にはたぶん行けると思う！調整してみる」
は？
たぶんってなに。調整って今からするの？一か月前のやつは調整じゃないのか？
ある程度保育園にお迎えに行く時間って決まっているし、ここを過ぎたらどんどん寝る時間が後ろ倒しになる。物理的に18時迎えが限界だ。家から3分の保育園。帰ってきて即、私が朝準備しておくレトルトのお弁当を食べさせて、お風呂に入れて、牛乳を飲ませて、歯磨きさせて、鼻水を吸引器で吸い取って、寝させる。ここまでノンストップじゃないと無理。
そもそも私は17時に迎えに行っているのを旦那が仕事したいだろうと思って保育園に相談して18時にしてもらったのだ。
数週間前にOKもらった時点でたぶん行けるかどうかの話はもうとっくに終わっている。はずだった。確認してもらってるはず。
無理だったら涙をのみながら、とっくに飲み会の誘いを断っていたはずだった。
これはいけないコースかな、とあきらめが過ぎりながら「いや、お迎え時間はたぶんとかじゃなくてマストだよ」と送って、いやこれは冷たいかな、私の無理を聞いてくれているわけだし…と旦那相手にめちゃくちゃ下手に出て、「忙しい中本当にごめんね＞＜上司に聞いてみてもらえると嬉しい…！ありがとう」と追加で送った
