The Fork in the Road: Job Hunting as a Principal Engineer vs. Director

Job hunting at the executive or principal level is a fundamental departure from the standard engineering search. At this altitude, the goal is no longer to demonstrate competency in coding or sprint management. Instead, you must prove your capacity to move the needle for an entire organization. While the end goal—organizational impact—is shared, the mechanisms for proving your value differ wildly between the Individual Contributor (IC) track and the Management track. ...

The AI Scapegoat: Is AI Really Behind the Big Tech Layoffs?

If you follow the business world, you’ve heard the drumbeat. Scarcely a week goes by without a major tech company—be it Google, Amazon, Meta, or Microsoft—announcing a new round of “restructuring.” Thousands of jobs are cut, and amidst the corporate-speak about “streamlining” and “finding efficiencies,” a new two-letter buzzword has taken center stage: AI. The official narrative is compelling. We’re told that new generative AI tools are so powerful, so efficient, that the company can suddenly achieve more with fewer people. Roles in customer service, HR, recruiting, and even entry-level coding are being automated. The layoffs, therefore, are not a failure of management, but an inevitable, futuristic step in technological progress. ...

Geoffrey Hinton: They’re spending $420 billion on AI. It only pays off if they fire you

Geoffrey Hinton is the Nobel Prize-winning academic known as the “Godfather of AI” for his foundational work on neural networks. He spent decades at Google, building the very technology that now powers our world. Then, he quit. He left his high-paying role so he could speak freely about the dangers of the technology he helped create. His warnings have ranged from existential risk to the “end of humanity.” But in a recent, stunningly blunt interview, Hinton swapped his philosopher’s hat for a CFO’s visor. He didn’t talk about paperclip-maximizing terminators; he talked about simple, cold, hard capitalism. ...

The Twilight of RAG: How LLM In-Context Ranking is Rewriting the Rules

For the past few years, Retrieval-Augmented Generation (RAG) has been the cornerstone of scaling Large Language Models (LLMs) to massive knowledge bases. Since early LLMs suffered from limited input length—with models like GPT-4 handling only about 8,192 tokens (roughly 12 pages)—RAG provided an elegant, if complex, workaround: retrieve the most relevant fragments and feed those to the LLM. However, the rapid evolution of LLMs and their specialized ranking capabilities, combined with exploding context windows, suggests that the traditional RAG architecture we built and optimized is fundamentally on the decline. ...

AGI is a Decade Away from Andrej Karpathy

In September 2024, Sam Altman published a blog post discussing “The Intelligence Age” and stated, “It is possible that we will have superintelligence in a few thousand days (!); it may take longer, but I’m confident we’ll get there”. In the whirlwind of AI advancements, it’s easy to believe that Artificial General Intelligence (AGI) is just around the corner. Every week, a new model is released that shatters previous benchmarks, writes better code, or creates more realistic images. The hype cycle suggests we are on the precipice of a new dawn. Yet, one of the most respected minds in the field, Andrej Karpathy, recently poured a dose of realism on the fire, stating that AGI is still “a decade away.” ...
