AGI Timelines: 2028 for Tax AI? 2032 for On-the-Job Learning?

Podcast host Dwarkesh discusses AGI timelines. He argues that while current LLMs are impressive, their lack of continuous learning severely limits their real-world applications. He uses the analogy of learning saxophone to illustrate how LLMs learn differently than humans, unable to accumulate experience and improve skills like humans do. This leads him to be cautious about AGI breakthroughs in the next few years but optimistic about the potential in the coming decades. He predicts 2028 for AI handling taxes as efficiently as a human manager (including chasing down receipts and invoices) and 2032 for AI capable of on-the-job learning as seamlessly as a human. He believes that once continuous learning is solved, AGI will lead to a massive leap, potentially resulting in something akin to an intelligence explosion.

The Async Queue Interview: An AI-Assisted Coding Challenge

2025-07-07

This blog post details a unique programming interview question: implementing an asynchronous queue, `sendOnce`, ensuring a single-threaded client only sends one request to a faulty server at a time. The interview assesses candidates' ability to handle tricky flag logic, debug code, program in a single-threaded environment, and adapt to new requirements (like minimum delays, batch sending, cancellation mechanisms, retries, etc.). The author also discusses AI's role in interviews, arguing that while AI can assist with coding, candidates still need code review skills; efficient AI tool usage is a new evaluation criterion.

Therapy Culture Is Killing Personality

2025-07-07

Therapy Culture Is Killing Personality

The author argues that the pervasive influence of therapy culture is eroding our language and understanding of self. Every personality trait is framed as a problem to be solved, leading to the over-diagnosis and medicalization of normal human behavior. Young people, in particular, are internalizing this, seeing mental health challenges as defining aspects of their identity. This over-explanation, the article contends, robs us of the mystery and romance of relationships and self-discovery, leaving a generation anxious and miserable. The author calls for a return to accepting the unexplainable aspects of being human.

Early Macintosh designers added the Apple logo to menu items to indicate keyboard shortcuts. Steve Jobs, however, deemed this excessive. A frantic search for a replacement led them to a Swedish campground symbol in an international symbol dictionary. This small, floral icon, chosen for its distinctiveness, remains a subtle part of macOS to this day, a hidden piece of design history.

The Norman Conquest and English Spelling: A Lost Story of Diacritics

The Norman Conquest and English Spelling: A Lost Story of Diacritics

This article explores how the Norman Conquest profoundly impacted English spelling. After 1066, French became the official language, and scribes carried over French writing conventions into English, resulting in letter combinations representing single phonemes, like "sh" and "th." The Renaissance saw French develop a system of diacritics through printing and standardization, while English retained the spelling conventions established during the Norman period. This explains why English lacks widespread use of diacritics today.

240Hz Monitor and Low-Latency Mouse: A Programmer's Precise Measurement

2025-07-06

A programmer, highly sensitive to latency, found a significant improvement after upgrading to a 240Hz monitor. However, switching USB ports for his wireless mouse introduced delays of around 10ms every few seconds. To precisely measure this, he developed a tool, found.as/l, that displays the delay between browser-rendered frames and pointer movements, along with pointer event batching and offsets. He also had to modify his xmit.toml to add CORS headers for high-precision timers. His observations were confirmed, leading him to avoid the problematic USB port.

The Walkman at 46: A Blast from the Past (and a Glimpse into a Dystopian Future)

The Sony Walkman's 46th anniversary prompts reflection on its controversial debut in 1979. Its lightweight design revolutionized personal music, but the rise of headphone-wearing pedestrians sparked anxieties about social isolation and public safety. Critics decried it as a symbol of individualism, even comparing it to a societal 'depressant'. Several US states enacted restrictions on headphone use while driving or cycling, with Woodbridge, New Jersey, famously banning headphone use while crossing the street – a law tested by Oscar Gross, who was fined for civil disobedience. This historical episode serves as a reminder that nostalgia often overlooks the initial resistance faced by new technologies, highlighting how the 'good old days' weren't always so good.
