Second Thoughts is a Substack publication run by Steve Newman that covers big issues in AI. It has over 7,000 subscribers and appears to be an honest personal newsletter, not a scam. The site has valid security — HTTPS is enforced, and there are no blacklists or malware flags. The domain is over a year old and registered with privacy protection, which is normal for an individual creator.
The biggest red flag is the 91 external scripts loaded on the page. That's a lot, and some could be trackers or analytics tools typical of the Substack ecosystem. It's not a sign the site is fake, but it could affect privacy or page speed. For a blog that doesn't process payments directly (subscriptions go through Substack), the risk is low. If you're considering subscribing, note that Bitcoin is mentioned as a payment option, which is irreversible — but that may be for donations or a separate offering.
Overall, secondthoughts.ai looks like a genuine publication. There are no deceptive signals, and the author is transparent about who they are. If you're interested in AI analysis, this seems like a reasonable source to follow.
