要点

  • この記事は、新しい技術が仕事を迅速化すると約束する一方で、結局は忙しさを増し、高付加価値の成果よりも浅いタスクへ努力を移すという、繰り返し現れるパターンを指摘している。
  • WSJの論考と、1,000社を超える企業にまたがる164,000人の労働者を対象に、AI使用の前後180日間を追跡したActivTrakの調査を引用しており、電子メール、メッセージ、チャットアプリに費やす時間は2倍を超えて増え、業務管理ツールの使用は94%増加したと報告している。
  • AIを利用する労働者の深く集中した作業に費やす時間はおよそ9%減少し、非利用者にはほとんど変化がなく、全体的なペースが速まる中で日常的なタスクへと傾くことを示している。
  • この現象は過去の技術革命にも見られるより広いパターンを反映している可能性があると論じ、忙しさをただ増やすのではなく、深い仕事を支えるAI導入を設計するための戦略を求めている。

Here’s a pattern I’ve observed again and again:

  • A new technology promises to speed up some annoying aspects of our jobs.
  • Everyone gets excited about freeing up more time for deep work and leisure.
  • We end up busier than before without producing more of the high-value output that actually moves the needle.

This happened with the front-office IT revolution, and email, and mobile computing, and once again with video-conferencing.

I’m now starting to fear that we’re beginning to encounter the same thing with AI as well.

My worries were stoked, in part, by a recent article in the Wall Street Journal, titled ​“AI Isn’t Lightening Workloads. It’s Making Them More Intense.”​

The piece cites new research from the software company ActivTrak, which analyzed the digital activity of 164,000 workers across more than 1,000 employers. What makes the study notable is its methodology: it tracked individual AI users for 180 days before and after they began using these tools, providing clear insight into what changed. The results?

“ActivTrak found AI intensified activity across nearly every category: The time they spent on email, messaging and chat apps more than doubled, while their use of business-management tools, such as human-resources or accounting software, rose 94%.“

The one category where activity was not intensified, however, was deep work:

“[T]he amount of time AI users devoted to focused, uninterrupted work—the kind of concentration often required for figuring out complex problems, writing formulas, creating and strategizing—fell 9%, compared with nearly no change for nonusers.”

This is a worst-case scenario: you work faster and harder, but mainly on shallow, mentally taxing tasks (because of all the context shifting they require) that only indirectly help the bottom line compared to harder efforts.
