Getting laid off stings. And then, somewhere between the initial shock and the job search anxiety, you sit down to update your resume and realize you have no idea what to do with the gap. Do you hide it? Explain it? Apologize for it? None of the above, as it turns out. The biggest mistake…
Everyone keeps asking the wrong question about AI and jobs. The real question isn’t “will AI take my job?” It’s “which jobs get more valuable as AI becomes more powerful?” And the answer might surprise you.
