Honestly, how far is the AI-induced layoff? (Blind)

  • dumpy: For junior, 2-3 years. Mid-level, 3-5 years. Senior, 5+ years. You’ll always need some high level engineers, those probably won’t go away.
  • beastmode$: If AI can do any coding task, nothing is stopping the laid off people from creating competitors to the big names. We will see a startup boom.

Layoff due to AI (Blind)

  • n0pants: AI is just an excuse. When they say they are letting go employees because of AI they are trying to fool the investors and reduce the head count at the same time.
  • TKTf28: AI is the last desperate attempt at keeping surveillance capitalism going and more importantly stopping a revolution triggered by the implosion of the whole economic and political system. 2024 is the end of the road for US dollar and its reserve currency status. War and layoffs are their way of saying we are willing to stay in power at any cost. They do not want to give up control. Generative AI is.a joke and a distraction.

Tech industry lays off nearly 80,000 employees in the first quarter of 2026 — almost 50% of affected positions cut due to AI (r/technology)

Backcountry Issue164 The Mountain Bellwether Summary

Generated by Codex with GPT-5

A ski career stretched into politics without losing its center

Susan Mangion’s “The Mountain Bellwether” treats Caroline Gleich’s 2024 U.S. Senate run less as a detour from skiing than as a change in altitude. Gleich enters the article as a familiar kind of mountain figure, a professional ski mountaineer whose public identity is built on bright outerwear, big objectives and years of climate and public-lands advocacy. What makes the piece interesting is that Mangion refuses to frame politics as a betrayal of that identity. Instead, she argues that Gleich’s campaign was an extension of the same commitments that already defined her life in the mountains.
