"Tuning frictional behavior on the fly has been a long-standing engineering dream," said co-author Katia Bertoldi of Harvard University. "This new insight into how surface geometry governs slip pulses paves the way for tunable frictional metamaterials that can transition from low-friction to high-grip states on demand.” In addition, the dynamics revealed by these results are similar to those of tectonic faults and thus give scientists a new model for the mechanics of earthquakes, according to their new paper published in the journal Nature.

“变”的是策略、方法与重心。平台必须变得更“重”，投入真金白银铺设数字基础设施，输出成熟的运营方法论，研发普惠的前沿技术，甚至担当维护公平市场环境的“裁判员”。其利润的来源，也日益体现为提供这些庞大而复杂的“重服务”所应得的回报。
OpenAI’s Codex CLI takes a similar approach with explicit modes: read-only, workspace-write (the default), and danger-full-access. Network access is disabled by default. Claude Code and Gemini CLI both support sandboxing but ship with it off by default.
