How to actually stay updated
Most “tech news” is noise. A small, deliberate set of sources beats trying to follow everything:
- One high-signal newsletter (e.g. The Verge, Ars Technica morning brief, or a curated AI digest)
- One deep-dive site for topics you care about (RTINGS for hardware, Stratechery or similar for business context)
- One YouTube channel that explains rather than hypes
- Ignore most social feeds — they optimize for outrage and novelty, not understanding
