THE NEXT RENAISSANCE: WHY CREATIVITY IS THE CURRENCY OF THE AI AGE

As AI automates repetitive tasks, human creativity, imagination, and the ability to ask better questions are becoming the most valuable professional assets. The World Economic Forum projects 92 million jobs displaced by 2030 but 170 million new roles created, with creative thinking among the fastest-growing skills in demand. Rather than competing with machines, the next decade will reward those who leverage AI for analytical tasks while applying uniquely human qualities like intuition, empathy, and visionary thinking.

BUILD SOMETHING SILLY

AI tools now let non-developers build custom software. This author rebuilt a website and created a personal invoicing tool using Cursor and Claude, replacing paid SaaS subscriptions. Wall Street has taken notice too, with SaaS stocks losing $285 billion after Anthropic released new AI tools, signaling a shift in how individuals and small businesses approach software. The key takeaway isn't any specific tool, but the mindset shift from "what should I subscribe to?" to "could I build this myself?" — a muscle best developed by starting small.

I INTERCEPTED 3,177 API CALLS ACROSS 4 AI CODING TOOLS. HERE'S WHAT'S ACTUALLY FILLING YOUR CONTEXT WINDOW.

Four AI coding tools had their context windows and token usage analyzed while fixing a specific bug in Express.js. Despite all tools successfully solving the bug, their token consumption varied a lot, with Gemini Pro using up to 350,000 tokens compared to Claude Opus's 23,000. Each tool used a distinct strategy: Opus was surgical but carried high tool definition overhead, Sonnet was methodical, Codex efficiently used Unix-like commands, and Gemini aggressively dumped vast amounts of data into its context.

YOUR AGENT FRAMEWORK IS JUST A BAD CLONE OF ELIXIR: CONCURRENCY LESSONS FROM TELECOM TO AI

Modern AI agent frameworks in Python and TypeScript are similar to the Elixir/Erlang BEAM virtual machine, which solved similar concurrency and fault-recovery challenges for telecom in 1986. The BEAM's actor model has features like isolated lightweight processes, message passing, and supervision trees, well-suited for the long-lived, non-deterministic interactions of AI agents.

STOP THINKING OF AI AS A COWORKER. IT'S AN EXOSKELETON

AI should be conceptualized as an exoskeleton that amplifies human capabilities, rather than an autonomous coworker. Physical exoskeletons enhance strength, reduce injuries, and improve endurance in fields like manufacturing and military, without replacing the human operator. AI should be used the same way.

MEASURING AI AGENT AUTONOMY IN PRACTICE

Anthropic's research analyzed millions of human-AI agent interactions across Claude Code and its public API to understand how agents are used in real-world contexts. It found that agents like Claude Code operate autonomously for longer periods, and experienced users grant them more independence (auto-approving more). Claude Code also proactively pauses for clarification more often than humans interrupt it on complex tasks.

FUNDRAISING STARTS BEFORE YOU NEED CAPITAL

Most founders lose the fundraising game by waiting until they need money to start pitching. The real process begins with building an investor prospect list and seeking feedback rather than capital to establish early relationships. By sending monthly updates and executing publicly, founders create scarcity and FOMO, often securing commitments before a round even officially opens.

THE SOFTWARE SHAKEOUT: WHAT IS DURABLE AND WHAT IS NOT IN THE AGE OF AI?

$1T in software market cap evaporated in three weeks. This framework sorts the survivors from the dead. Software in the path of doing work (CrowdStrike, Stripe, Shopify) is durable. Software that generates paperwork about work (DocuSign, Monday.com, Zendesk) gets replaced by AI that just does it. The scary middle - Atlassian, Salesforce, HubSpot - is eroding slowly but the cliff is coming. If you're building a product that humans fill out so other humans can read, rethink the entire premise before your next board meeting.

HIRING FOR A NEW ROLE/FUNCTION FOR YOUR FIRST TIME? DO THIS FIRST.

A bad first hire in a new function costs you a year. The fix takes one week. Before you write the JD, do 5-10 calibration calls with people who already hold the role at companies one stage ahead of yours. You'll learn what "great" actually looks like, what comp is real, and which interview questions actually separate the best from the mediocre. Most founders skip this step and end up hiring on vibes. Don't be that founder.

ADVICE WE REJECTED TO BECOME ONE OF THE FASTEST GROWING START-UPS EVER

Deel co-founder Shuooo Wang details how the company scaled by ignoring traditional startup "best practices," such as hiring a VP of Sales early or focusing on the SF talent pool. Instead, Deel prioritized founder-led sales to maintain customer context, hired for traits over pedigree, and invested in 100+ local entities to build a moat around compliance and reliability. By favoring frugality and vertical M&A over high burn, the company leveraged first-principles thinking to become one of the fastest-growing startups.

AGAINST “AGAINST TASTE”

Taste is informed judgment built through experience rather than passive curation. True taste is exercised during the creation process through invisible, compounded decisions that lead to elegance and coherence.

THERE IS NO PRODUCT

If you remove the difficulty, you remove the product. If it only takes a weekend to build a product, then anyone else could do it in a weekend, too. You can't just add features and hope the market comes back, because there's no core product. Some software will still be an asset, but most of it will become inventory, and every model generation will push that line further.

IN DEFENSE OF VERTICAL SOFTWARE

The industry is currently asking why vertical software needs to exist when AI companies are pouring billions of dollars into building the most powerful general-purpose AI systems in the world. Enterprise software is just code, but that's not where the value of software comes from. The value of enterprise software comes from understanding the process and the organization well enough to make the software do exactly the right thing.

ALMOST IMPOSSIBLE: JAVA DESERIALIZATION THROUGH BROKEN CRYPTO IN OPENTEXT DIRECTORY SERVICES

Searchlight Cyber (Assetnote) discovered an unauthenticated Java deserialization vulnerability in OpenText Directory Services (OTDS) exploitable in its default configuration, stemming from a flawed HMAC signature verification where attacker-controlled length fields allowed truncating the signed message to begin at an injected payload. Exploitation required building a custom Deflate compressor with tailored Huffman codes to produce output restricted to valid modified UTF-8 bytes (0x01-0x7F) while remaining incompressible by zlib, enabling the payload to survive a double-compression pipeline intact. Organizations running OTDS should patch immediately, as a compromise could affect all integrated OpenText applications that rely on it for authentication.

RED VULNS RISING: EXAMINING CHINESE NATIONAL VULNERABILITY DATABASES

Bitsight analyzed China's two national vulnerability databases—CNNVD, overseen by the Ministry of State Security, and CNVD, operated by CNCERT—and found that while they largely mirror CVE publication, approximately 1,400 entries were published in Chinese databases before becoming public in CVE, often by several months. China's 2021 RMSV regulations tightened domestic vulnerability disclosure controls, including mandatory 48-hour reporting to the government and prohibitions on sharing PoC exploits. There was a notable decline in non-CVE vulnerability publications from CNVD after the regulation, although CNNVD has recently seen a resurgence. Security leaders should account for potential blind spots in Western vulnerability ecosystems, as some Chinese database entries lack CVE equivalents and may represent vulnerabilities unknown to Western defenders.

DECRYPTING MULTIDESK PASSWORDS

MultiDesk RDP client's password encryption was reverse-engineered, revealing RC4 encryption with per-user keys stored in the HKEY_CURRENT_USER\Software\MultiDesk\key registry hive across both legacy (v3.16) and modern (v14.0) versions. Version 3.16 used base64-encoded RC4 ciphertext with rdtsc-generated keys, while version 5+ introduced a salted key derivation scheme using CryptGenRandom, but remained fundamentally RC4-based. Pentesters should add MultiDesk.xml, MultiDesk.multidesk, and the associated registry keys to their internal recon checklists, as credential recovery is trivial with local admin or user-level access to the target machine.
