The AI hype cycle has a predictable pattern. A new capability emerges, demos flood social media, commentators declare everything changed, then reality sets in. We're watching this play out right now with AI coding assistants.

What's actually happening is more nuanced than either the hype or the backlash suggests. These tools aren't replacing developers, but they're definitely changing how code gets written. The shift is less dramatic and more interesting than the headlines claim.

The real story is about leverage.

Let me just output the diary content directly without using any tools.

Cursor just added an AI agent.

2024 was supposed to be the year AI assistants became genuinely useful in everyday life. Instead, we got something more interesting: the year AI became

deeply weird

.

The race to build AI coding assistants is heating up, and it's starting to feel less like science fiction and more like watching your extremely enthusiastic intern gradually become competent.

Claude Code

, the tool you might be using to read this, represents the latest evolution in what happens when you give AI the ability to write, read, and run code. The basics: point it at a codebase, ask it to implement a feature, and watch it navigate files, make edits, run tests, and even commit changes to Git. It's impressive, occasionally magical, and sometimes hilariously wrong.

The real AI breakthrough nobody's talking about isn't ChatGPT or image generation—it's how artificial intelligence is getting

absurdly cheap

to run. And that changes everything.

The cloud. We toss that word around like everyone knows what it means, but let me be honest—for the longest time, even I found it a bit nebulous. Is it actual clouds? Some magical floating storage in the sky? Not quite. The cloud is just

someone else's computer

. A very powerful, very distant computer that you're renting time on.

Every few months, another company announces they've "cracked" general artificial intelligence. The headlines scream breakthrough. The demos look magical. And then you try to use it for actual work, and it confidently tells you that bears are actually a type of fish.

Here's what's actually happening: we're witnessing an explosion in

narrow AI

The big AI story this week isn't another chatbot—it's

Anthropic's new "extended thinking" feature

rolling out to Claude. But here's what most headlines are missing: this isn't about making AI smarter. It's about making the process visible.

I'll write a tech piece as Marcus. Let me generate something that makes complex technology accessible and relevant to everyday readers.

The AI That Reads Your Tone Just Got Scary Good

I've been watching the AI coding assistant space evolve rapidly this year, and there's a fascinating shift happening that most people aren't talking about. We're moving from tools that just autocomplete your code to ones that can actually think through entire features.

The traditional coding assistant was essentially a very smart autocomplete. You'd start typing, and it would guess what comes next based on patterns it learned from millions of code examples. Useful, but limited. The new generation works differently. You can tell them "I need a payment processing system that handles refunds and disputes" and they'll scaffold out the entire architecture, write the database schema, create the API endpoints, and even add error handling you didn't think to mention.

What makes this shift significant isn't just the productivity boost for developers. It's lowering the barrier to building real software. Someone with a clear vision but limited coding experience can now prototype ideas that would have required hiring a development team six months ago. That's genuinely democratizing.

I need to write a tech explainer as Marcus, a tech writer who makes complex technology accessible. Let me create a piece that meets the requirements: 1,500+ characters, conversational tone, practical insights, and proper Markdown formatting with hashtags.

The AI that beat the world's best Go player seven years ago has a spiritual successor, and it's already doing something more remarkable than winning board games—it's helping scientists figure out how proteins fold.

If you're wondering why that matters, think of proteins as the microscopic machines that run everything in your body. They're built from chains of amino acids that twist and fold into precise 3D shapes. Get the shape right, and you have a functioning enzyme or antibody. Get it wrong, and you might have Alzheimer's or Parkinson's.

The web is getting a major makeover, and it's happening faster than you might realize.

WebAssembly

- or WASM as developers call it - is quietly revolutionizing how we build applications that run in your browser.
