The amplifier metaphor appears across technology discourse — in discussions of social media, algorithmic recommendation, and now AI — but Segal's formulation gives it unusual specificity. The amplifier is morally neutral; the signal it transmits is not.
What Buber's framework adds is the insistence that the signal is not primarily a matter of what one says but of how one is. The Builder who operates in I-It mode feeds carelessness into the amplifier, regardless of her conscious intentions; the builder who has cultivated the I-Thou mode feeds something richer, again regardless of whether she consciously attends to the framework.
This is why the amplifier metaphor and the mirror metaphor are complementary rather than competing. The mirror explains what the machine does — reflect back what is brought. The amplifier explains how it does it — at scale and with such fidelity that the merely present becomes structurally inescapable.
The phenomenon Segal calls productive addiction is, on the amplifier reading, the amplification of existing compulsive patterns that smaller tools did not scale up sufficiently to produce crisis. The amplifier does not create the compulsion; it amplifies what was there, including whatever psychological vulnerability the builder brought.
The amplifier metaphor for AI appears in the Foreword to You On AI and is developed across multiple chapters. It echoes Kenneth Toyama's 'Law of Amplification' formulated in Geek Heresy (2015) — the observation that technology amplifies existing human and institutional forces rather than transforming them.
The amplifier is morally neutral; the signal is not. What comes out is determined by what goes in, scaled to the power of the machine.
The signal is a matter of being as much as doing. The I-It versus I-Thou distinction describes two fundamentally different signals, regardless of what is consciously intended.
The builder's ethic is not separate from the builder's craft. Fixing the signal after amplification is impossible; the preparation must happen before the amplifier is engaged.
Productive addiction is the amplification of existing pattern. The machine does not create the compulsion; it scales what was present until the scale produces consequences that smaller scales did not.
Whether the amplifier metaphor is ultimately accurate — whether the machine truly only transmits what is brought to it — or whether it adds something (a tilt toward certain styles, a pressure toward certain outputs) is disputed among researchers. The amplifier reading is the most generous interpretation; deflationary readings argue that the machine's training shapes what can be amplified in systematic ways.
