What this article is about

This summary covers The Economist’s April 11th, 2026 Business article listed in the contents as A dangerous new AI and published under the headline Mythical monster.

The article argues that warnings about AI danger are usually worth treating with skepticism, because frontier labs have incentives to dramatise their own progress. This time, though, The Economist thinks the warning may be genuine. Its focus is Anthropic’s latest model, Mythos, which the company says is powerful enough at discovering and exploiting software flaws that it should not yet be released broadly.

A film story that is really about systems

Carl Weiseth’s article starts as a behind-the-scenes look at the speedriding film “L’Experience Magnifique,” but its real subject is the hidden infrastructure required to make spectacular mountain footage possible. The finished images may look effortless: tiny wings cutting down steep alpine faces, drone shots threading through gullies, skiers and pilots moving as if the mountain were an open playground. Weiseth makes clear that none of that ease is real. Every successful run depends on planning, communication, weather judgment, transport improvisation, and a group of people who understand that small mistakes in this environment can compound very fast.

The article argues that the debate is framed the wrong way

Liam McGee’s “Online or In-Person?” starts with a question that sounds simple and familiar in modern outdoor education: if backcountry skiers can learn from videos, Zoom courses and polished online modules, how much does old-fashioned in-person instruction still matter? McGee answers by putting himself in the middle of both systems. Before joining an introductory ski-mountaineering course in Idaho’s Sawtooths, he studies online material from mountain guide Mark Smiley, practices knots at home and shows up with a decent store of concepts already in his head. On the bootpack, though, he quickly discovers that knowing the words is not the same thing as understanding how they live in terrain. Niels Meyer, the Sawtooth Mountain Guides co-owner leading the group, keeps answering McGee’s questions with some version of “it depends,” because every answer changes with angle, snow texture, partner position and immediate hazard.

• Difficulty: HARD
• Problem: Largest Rectangle in Histogram
• Main tags: Array, Stack, Monotonic Stack

What the problem is really asking

Each bar in the histogram has width 1, and the goal is to find the largest possible rectangle that can be formed by taking one or more adjacent bars.

• Problem: LRU Cache
• Main tags: Hash Table, Linked List, Design, Doubly-Linked List

What the problem is really asking

This problem is not mainly about storing key-value pairs. It is about building a data structure that can answer two different questions at the same time:

• Difficulty: MEDIUM
• Problem: Find Peak Element
• Main tags: Array, Binary Search

What the problem is really asking

This problem does not ask for the maximum value in the whole array.

It only asks for any index whose value is greater than its neighbors. That is a much weaker requirement, and that weaker requirement is exactly what makes the binary-search solution possible.

• Problem: Product of Array Except Self
• Main tags: Array, Prefix Sum

What the problem is really asking

For each index, the answer should be the product of every number except the one currently sitting at that index.

If the input is [1, 2, 3, 4], then:

• Difficulty: MEDIUM
• Problem: Longest Repeating Character Replacement
• Main tags: Hash Table, String, Sliding Window

What the problem is really asking

The input is a string and a budget k. One operation lets us replace any single character with any other character. The goal is to find the longest substring that can be turned into a string of all one repeated character using at most k replacements.
