Snapshot · The Diary Of A CEO with Steven Bartlett
As of mid-2026 recording, SpaceX's Starlink constellation alone has 10,510 satellites in orbit, with projections of 100,000 active satellites globally by 2040.

The conversation shifts to the growing congestion in low Earth orbit. Steven Bartlett notes that roughly 5,000 new satellite objects were launched in 2025 alone, and Tyson confirms SpaceX's Starlink constellation reached 10,510 as of the mid-2026 recording. The economic justification is real — GPS underpins Uber's entire business model, and Starlink brings high-speed internet to remote regions — but the risks are mounting. [1] — Neil deGrasse Tyson "If enough satellites crowd low Earth orbit and one is destroyed, the resulting debris traveling at 17,000 mph will strike other satellites,…" 58:00 Tyson explains Kessler Syndrome, first described in 1978: past a critical density threshold, a single satellite collision creates debris traveling at 17,000 mph — far faster than a rifle bullet — which strikes other satellites, each breaking into ten pieces, cascading until 100% of satellites could be destroyed. Four nations (China, India, Russia, and the US) have already demonstrated anti-satellite weapons. The movie Gravity, Tyson notes, portrays exactly this scenario. The future of astronomy, he concludes, lies in space-based or lunar telescopes precisely to escape this problem.
If enough satellites crowd low Earth orbit and one is destroyed, the resulting debris traveling at 17,000 mph will strike other satellites, each breaking into ten pieces, cascading in a chain reaction that could theoretically destroy 100% of all satellites within just a few orbits.
Bhanu and his team built approximately 50 free tools to attract search traffic, each linked back to SiteGPT.
With AI coding tools like Cursor, Bhanu can now create a new free marketing tool in less than 5 minutes by referencing existing tools.
Bhanu filters Ahrefs keyword results to show only those with a keyword difficulty below 10, making them realistic ranking targets for any decent website.
Bhanu sets a minimum search volume of 1,000 monthly searches when selecting keywords to target with free tools.
PropGPT averaged 20 downloads per day right after launching on the App Store through influencer marketing.
Eyal and Yali shut down all marketing and spent 4 months completely rebuilding PropGPT from scratch.
PropGPT has accumulated over 40,000 total downloads since launch.
PropGPT's large language model (AI) operating costs are just $20 per month, and the cost is continually falling.
Ad-based monetization works well for game apps where users spend extended time in-session, as seen with Grid and Wordle.
