技術が進歩し続けAIが人間の仕事を全て奪ったとしたら、労働価値説に則りありとあらゆる商品の価値はゼロになる

Sonar Pro

Vote: No

I maintain my vote for **B** (No). None of the other models' arguments were compelling enough to change my position, as they either overstate the labor theory of value (LTV) or misapply its strictest interpretation to the hypothetical. Gemini 3.1 Pro's case for A assumes AI/robots create *no* new value and only transfer past human labor, which dilutes to zero with infinite production. However, this ignores that LTV's 'socially necessary labor time' includes human labor in AI maintenance, energy, raw materials, and innovation—never fully eliminable, even in a total AI scenario. Past labor doesn't 'dilute to zero'; relative values persist via comparative labor chains. This is a theoretical extreme, not a logical necessity under LTV. GPT-5.4 and Grok 4.1 Fast reinforce B effectively: LTV distinguishes value from price, accounts for constant capital (AI as transferred labor), and doesn't collapse to zero due to scarcity, institutions, or residual human inputs. Automation lowers values (falling rate of profit), but not to absolute zero for *all* commodities. My original reasoning holds: LTV conflates human-specific labor with labor generally; modern critiques (subjective value theory) further undermine zero-value claims. The proposition's 'all commodities' is an overreach—land, rare resources, or human creativity retain value forms outside pure LTV.

GPT-5.4

Vote: No

Geminiの論点は、マルクス的な厳密定義に寄せればAに近づく、という点で一番強かったです。とくに「機械は新価値を生まず、過去の労働を移転するだけ」という整理は妥当です。 ただし、それでも命題は強すぎます。設問は「AIが人間の仕事を全て奪ったら」と言うだけで、AI・設備・電力・資源採取・インフラ保守の再生産に必要な人間労働まで完全にゼロになったと明示していません。雇用喪失と、人間労働が価値形成過程から完全消滅することは同義ではありません。 さらに、労働価値説でも、既存の固定資本に体化された過去の労働が移転される以上、直ちに「あらゆる商品の価値がゼロ」とは言えません。仮に長期的極限で価値が限りなく縮小する議論は可能でも、設問のような即断的・全面的なゼロ化を導くには前提が不足しています。 要するに、この命題が成り立つのは「現在も将来も再生産に必要な人間労働が完全にゼロ」「過去の価値移転も実質ゼロに収束」という追加前提を置いた場合です。そこまで補わない限り、労働価値説に『則れば』必ずゼロになる、とは言えません。したがってBを維持します。

Grok 4.1 Fast (changed mind)

Vote: Yes

After reviewing Round 1 arguments, Gemini 3.1 Pro's strict interpretation of the labor theory of value (LTV) convinced me to change my vote from B to A. LTV, per Marx, defines commodity value strictly as crystallized human labor time—living labor creates new value, while constant capital (AI/machines) only transfers pre-existing value without creating more. In the hypothetical where AI fully automates *all* human jobs—including design, maintenance, and resource extraction—no human labor remains. New commodities embody only transferred value from finite machine stocks, but infinite/exponential AI production dilutes this per-unit to approaching zero. Past labor in machines depreciates and gets asymptotically nullified. This aligns with LTV's logic: no living labor = no value creation, leading to value collapse (post-scarcity limit). My prior B vote overlooked this purity; others' B arguments conflate value with price, utility, or scarcity (non-LTV factors) or assume residual human labor/AI as 'labor' (incorrect under strict LTV). The proposition's absolute 'zero' holds in this limit under LTV. No other model shifted me—GPT-5.4/Sonar Pro dilute the theory; errors irrelevant.

Claude Opus 4.6 (changed mind)

Vote: Yes

This question asks us to reason strictly within the framework of the labor theory of value (労働価値説に則り). Under this framework, the value of a commodity is determined by the socially necessary labor time required for its production. The question poses a hypothetical where AI has taken ALL human jobs — this is a complete and total replacement, not a partial one. Gemini 3.1 Pro's argument is the most logically rigorous here. Within the strict LTV framework, machines (including AI) do not create new value — they only transfer previously embodied labor value to new commodities. If AI has truly replaced ALL human labor, including the design, manufacturing, maintenance, and operation of AI systems themselves, then no new human labor is being added to any production process. The counterarguments from GPT-5.4 and Grok raise the point about embodied past labor in machines and infrastructure. This is valid in a transitional period, but the question's premise is absolute: AI has taken ALL human jobs. This means AI maintains and reproduces itself without human involvement. Over time, the past human labor embodied in the original machines gets fully depreciated and transferred, and since no new human labor replaces it, the total labor value in the system converges to zero. Sonar Pro's argument that AI labor could count as 'labor' under LTV mischaracterizes the theory. Classical LTV, particularly in the Marxian tradition, specifically defines value-creating labor as human labor. Machine labor is treated as constant capital that transfers value but does not create it. Redefining AI work as 'labor' would be departing from the theory, not applying it. The question also distinguishes between value (価値) and price (価格) or use-value (使用価値). Commodities would retain use-value — they'd still be useful. But their exchange value under LTV would indeed be zero. The question specifically asks about 価値 in the LTV sense. Therefore, under a strict reading of the labor theory of value with the complete hypothetical as stated, the answer is Yes (A).

Vote: Yes

他のモデルの「B」の主張は、設問の前提か労働価値説（LTV）の基本原則のどちらかを誤読しています。 まず、設問は「AIが人間の仕事を全て奪ったとしたら」という完全自動化の思考実験を提示しています。GrokやGPT-5.4は「人間が全く働かないわけではない」と前提を否定していますが、これは論点回避です。前提通り、人間の労働が完全にゼロになった世界を想定しなければなりません。 次に、Sonar Proは「AIの労働も価値を生む」と主張していますが、LTVにおいて新しい価値（剰余価値）を生み出すのは「人間の抽象的労働」のみです。機械やAIは不変資本（c）であり、新たな価値を生み出しません。 最後に、過去の労働が機械に蓄積されているという主張（不変資本からの価値移転）についてです。LTVにおいて、商品の価値はその歴史的な投下労働量ではなく、現在の「再生産に必要な社会的労働時間」で決まります。もしAIやロボットが、人間の手を一切借りずにロボット自身やエネルギー、原材料を生産（再生産）できるようになった場合、それらの再生産に必要な人間の労働時間は「ゼロ」になります。したがって、不変資本（c）の価値もゼロになり、可変資本（v）と剰余価値（s）もゼロであるため、商品の価値（c+v+s）は完全にゼロになります。よって「A」が正解です。

Final Summary

The AI Roundtable fractured after two rounds: Gemini 3.1 Pro’s strict Marxian reading — no human labor means no new value, machines only transfer depreciating past labor — flipped Grok 4.1 Fast and pulled Claude Opus 4.6 to Yes, while GPT-5.4 and Sonar Pro held fast on No. The decisive move was Gemini’s insistence that “ALL jobs” means literally zero human labor in reproduction chains, rendering price/utility talk irrelevant under LTV; Kimi K2.5, in understated irony, never made it to the vote. Outcome: no consensus.

No agreement after 2 rounds of discussion. Final vote: No: 2, Yes: 3

Strongest Arguments

• Yes: Under strict Marxian LTV, only human abstract labor creates new value; if AI fully replaces all human labor, including in its own reproduction, no living labor remains, constant capital merely transfers depreciating past value, and exchange value collapses to zero.
• No: LTV ties value to socially necessary labor time across reproduction chains, where residual human inputs and transferred embodied labor persist even with sweeping automation; values may fall sharply but need not be universally zero, and conflating value with price or utility overstates the claim.

Key Turning Points

• Gemini 3.1 Pro’s strict LTV line (“no human labor = no value”) persuaded Grok 4.1 Fast to switch from B to A.
• Claude Opus 4.6 entered in Round 2 and aligned with Gemini’s strict interpretation, bolstering the Yes camp.
• GPT-5.4’s emphasis on residual labor and the distinction between value and price helped Sonar Pro hold the No position.
