Final Demo Quotes

Imagine el lector un sistema que, en palabras de la famosa canción de Police, vigile cada bocanada de aire que inhale, cada movimiento que haga y cada lazo que rompa. Un sistema que supervise su cuenta bancaria y su ritmo cardíaco, sus niveles de azúcar y sus aventuras sexuales. Es evidente que conocerá al lector mucho mejor de lo que este se conoce a sí mismo. Los autoengaños y las ilusiones que hacen que la gente quede atrapada en malas compañías, carreras equivocadas y hábitos perniciosos no engañarán a Google. A diferencia del yo narrador que nos controla en la actualidad, Google no tomará decisiones a partir de relatos amañados, no caerá en la trampa de atajos cognitivos ni se guiará por la regla de la «arte culminante-parte final». Google recordará en verdad cada paso que demos y cada mano que estrechemos. Muchas personas estarán encantadas de transferir gran parte de sus procesos de toma de decisiones a manos de un sistema de este tipo, o al menos de consultar con él siempre que se enfrenten a decisiones importantes. Google nos aconsejará qué película ver, adónde ir de vacaciones, qué estudiar en la universidad, qué oferta laboral aceptar e incluso con quién salir y casarse. «Oye, Google —le dirá—, tanto John como Paul me cortejan. Los dos me gustan, pero de una manera diferente, y me está costando mucho decidirme. Considerando todo lo que sabes, ¿qué me aconsejas que haga?» Y Google contestará: «Bueno, te conozco desde el día que naciste. He leído todos tus correos electrónicos y registrado todas tus llamadas telefónicas y conozco tus películas favoritas, tu ADN y el historial completo de tu corazón. Tengo datos exactos acerca de cada cita que has tenido y, si quieres, puedo mostrarte gráficos segundo a segundo de tu ritmo cardíaco, tensión arterial y niveles de azúcar de cada vez que quedaste con John o con Paul. Si es necesario, incluso puedo proporcionarte una puntuación matemática precisa de cada encuentro sexual que tuviste con uno u otro. Y, naturalmente, los conozco tan bien como a ti. Sobre la base de toda esta información, de mis magníficos algoritmos y de estadísticas sobre millones de relaciones que hace décadas que reúno…, te aconsejo que te quedes con John, ya que tienes un 87 por ciento de probabilidades de vivir a la larga más satisfecha con él. »De hecho, te conozco tanto que también sé que no te gusta esta respuesta. Paul es mucho más guapo que John, y puesto que concedes tanto peso a la apariencia externa, querías secretamente que yo te dijera ”Paul”. La apariencia es importante, desde luego, pero no tanto como crees. Tus algoritmos bioquímicos (que evolucionaron hace decenas de miles de años en la sabana africana) conceden a la apariencia un 35 por ciento de la puntuación global de parejas potenciales. Mis algoritmos, que se basan en los estudios y las estadísticas más actualizados, dicen que el aspecto solo tiene un 14 por ciento de impacto en el éxito a largo plazo de las relaciones románticas. Así, aunque he tenido en cuenta la apariencia de Paul, continúo diciéndote que estarás mejor con John».[31] A cambio de estos devotos servicios de asesoramiento, solo tendremos que abandonar la idea de que los humanos son individuos, y de que cada humano tiene un libre albedrío que determina qué es bueno, qué es hermoso y cuál es el sentido de la vida. Los humanos ya no serán entidades autónomas dirigidas por los relatos que inventa su yo narrador. En cambio, serán parte integral de una enorme red global.

Max Levchin’s Plan A was not to be. Demand for security on handheld devices never materialized. He remained a vagabond. But he was cooking another idea. Max pursued a Plan B that centered on cryptography software. “It’s really cool, it’s mathematically complex, it’s very secure,” said Levchin.7 But once again, no one really needed it. Plans C, D, and E didn’t work out any better. Levchin’s Plan F, still based on his cryptography expertise, was a system for securely transferring cash from one PalmPilot to another. As part of that effort, Levchin’s team built a Web-based demo version that did everything on a Web site that the PalmPilot version could do. By early 2000, people were using the Web version for actual transactions, and the growth of the Web demo was more impressive than for the handheld version. “Inexplicable,” recalled Levchin. “The handheld one was cool and the Web site was … unsexy … a demo. Then all these people from a site called eBay were contacting us and saying, ‘can I put your logo in my auction?’ We told them ‘No. Don’t do it.’ Eventually, we realized that these guys were begging to be our users. We had the moment of epiphany. For the next twelve months, we just iterated like crazy on the Web site version.”8 Levchin finally had a tool that filled a void, allowing ravenous eBay traders to safely transfer cash from buyer to seller. Plan G—a little outfit called PayPal—was born. And did it strike gold. PayPal is the now dominant system of paying securely for online purchases. Eventually, eBay, whose internally run payment system was floundering, bought PayPal for $1.5 billion.

The idea of dividing our work into smaller units isn’t new. You’ve probably heard this advice a hundred times: if you’re stuck on a task, break it down into smaller steps. Every profession and creative medium has its own version of “intermediate steps” on the way to full-fledged final works. For example: “Modules” in software development “Betas” tested by start-ups “Sketches” in architecture “Pilots” for television series “Prototypes” made by engineers “Concept cars” in auto design “Demos” in music recording

What can explain this difference? On the surface, much appears to hinge on Richard’s programming feat, his software shim. Otherwise, his effort with Konqueror seems much like my struggles with Mozilla. Perhaps he was just a better programmer than me, and without his coding cleverness, there would be no story. That explanation is too simple. Richard made his shim only after determining he needed one last link in a chain of inspiration, intuition, reasoning, and estimation. His shim was a consequence of his overall plan. To show what I mean, here’s an accounting of what Richard did in his first couple of days at Apple. He began by quizzing us on the browser analysis we had done before his arrival, and after hearing it, he quickly discarded our effort with Mozilla as unlikely to bear fruit. By doing so, he demonstrated the self-confidence to skip any ingratiating display of deference to his new manager, a person who had years of experience in the technical field he was newly entering. Next, Richard resolved to produce a result on the shortest possible schedule. He downloaded an open source project that held genuine promise, the Konqueror code from KDE, a browser that might well serve as the basis for our long-term effort. In getting this code running on a Mac, he decided to make the closest possible approximation of a real browser that was feasible on his short schedule. He identified three features—loading web pages, clicking links, and going back to previous pages. He reasoned these alone would be sufficiently compelling proofs of concept. He then made his shortcuts, and these simplifying choices defined a set of nongoals: Perfect font rendering would be cast aside, as would full integration with the Mac’s native graphics system, same for using only the minimum source code from KDE. He reasoned that these shortcuts, while significant, would not substantially detract from the impact of seeing a browser surf web pages. He resolved to draw together these strands into a single demo that would show the potential of Konqueror. Then, finally, he worked through the technical details, which led him to develop his software shim, since that was the only thing standing between him and the realization of his plan. His thought process amplified his technical acumen. In contrast, Don and I were hoping Mozilla would pan out somehow. I was trying to get the open source behemoth to build on the Mac, with little thought beyond that. I had no comparable plan, goals, nongoals, tight schedule, or technical shortcuts.

There I sat as my dad and the salesperson walked down the aisle. My dad seemed to take some particular interest in the video game that I had just been playing. Maybe interest is too weak of a word, because my dad became engrossed with the demo. I spent the next forty-five minutes crouched behind the boxes across the aisle, waiting for my dad to get bored and to move along. He never moved. Actually, it was pretty impressive how well he did on the game. In that time, he beat three levels and unlocked a few hidden treasures that I never even heard of. I’m starting to wonder if the reason why he’s always telling me to get off the video games is so he can play himself. The salesman urged him a few times to see other set-ups and even try other games, but my dad had none of it. He was like a man possessed on that controller. The whole time, my back was growing sorer from crouching under the shelf and my butt was starting to go numb. Finally, as it came closer to the time he had to leave to pick me up, he graciously thanked the salesman for his time. When they walked away, I burst out from behind the boxes ready to sprint. I needed to beat my dad outside, but the first stride I took sent me collapsing to the ground. Both legs were fully asleep! I shook them like crazy to get the blood flowing back into them. A man walked by with a frightened look on his face, shielding his young son from the sight of me. By the time I got my feet to stop tingling, it was too late. I ran to the front of the store just in time to see my dad get into his car. At that point, I should have cut my losses and admitted to the charade. At least this way, I would have had a ride back. But that’s not how it happened. At that moment, I was sure I could sprint back to the library faster than he could drive there. Three traffic lights stood in between Good Buys and the library. I was counting on a little help from the big Guy upstairs to make those lights red for as long as possible.
