Rowan Cheung engagement report
@rowancheung - 596K followers on X
Measured over 8 original posts from a 30-day window, last computed on August 26, 2026.
Engagement
A typical post picks up 273 interactions against 596K followers, an engagement rate of 0.046%. Measured over 8 original posts, its engagement rate beats 57% of 3,774 tracked accounts of a similar size, which puts it in the middle of its size range rather than at either end. Posts are seen about 45K times each, and 0.601% of those impressions turn into an interaction. That is about 7.61% of the follower count, which is the gap between an audience on paper and an audience in a timeline. Posting runs at about 1.2 post a day over the last 30 days, though only 37% of days saw any activity at all. Most posts go out around 15:00 UTC, and Monday is the busiest day of the week. Of the 8 posts sampled, 75% carry an image or video and 100% are part of a thread. The account's strongest tracked post pulled 1.7K interactions, about 6.3x its own typical post.

Compared with accounts its own size
Rowan Cheung's engagement rate beats 57% of the tracked X accounts closest to it in follower count (3,774 accounts, accounts of similar size (decile 8 of 10)). A percentile is spread evenly by construction, so 50 really is the middle of that group and 90 really is its top tenth.
On engagement per impression rather than per follower it beats 39% of the same group. When those two numbers disagree, the gap is about how far its posts travel rather than how people react to them.

At 0.046%, Rowan Cheung sits above the 25th percentile of the 36,521 accounts in this comparison. That places it in the below the median band, which runs 0.012% to 0.08%.

Posting timing
This account posts most often around 15:00 UTC, and Monday is its busiest day of the week. The bars below are the catalog-wide pattern, with this account's own busiest slot marked. They do not show how this account performs at each hour: we keep one aggregate per account, not one per hour, so that measurement does not exist in our data.

MIT researchers just replicated human muscles with AI-controlled fibers. Inside each fiber is a sealed tube of electrically charged liquid and a tiny electric pump. When the pump activates, one side contracts while the other relaxes, just as your biceps and triceps do when you bend your arm. How it works: > The pump injects electrical charge into the fluid > This creates ions that drag the liquid along with them > No motors, no external pumps, completely silent Because they're fibers, they bundle together just like real muscles, scaling up force by adding more strands. In demos, these fibers were strong enough to bend a robotic arm and curl a dumbbell... but gentle enough to shake someone's hand. From prosthetics to exoskeletons to industrial robots, this is what happens when engineers stop building around motors and start building around biology.

Mark Zuckerberg is running Meta's superintelligence lab like a startup. When I interviewed him, he told me the principles on how he built the team: "You don't need many hundreds of people. You need 50 to 100 people. It's a group science project who can keep the whole thing in their head at once. Seats on the boat are precious." "If someone is not pulling their weight on that, it has this huge negative effect in the way that it doesn't have on other parts of the company" "I wanna know who the top AI researchers are, and I wanna personally have relationships with them, and build the strongest team we can." His rules for running it: - If someone isn't pulling their weight, it has an outsized negative effect, so he personally went out and recruited every top researcher himself - No top-down deadlines. "It's research. You don't know how long the thing is gonna take." - Keep the org flat. No non-technical management layers, because once someone stops doing the work, "the knowledge decays."

There's a startup trying to build data centers in the ocean. And it's INCREDIBLY fascinating: Mass consumption of electricity and water is a growing bottleneck for data centers. So by moving offshore, it eliminates both problems -- the ocean provides unlimited cooling, and the waves provide unlimited power. There are also no engines, so the data centers drive themselves to their destination by using the shape of their hull to propel through waves. Called Panthalassa.

A missile engineer got tired of mosquitoes... so he built an autonomous drone that hunts them Malaria kills over 600,000 people every year, most of them children under 5, so this could save millions of lives Here's how it works: > Each drone weighs 40 grams (lighter than a golf ball) > It fires ultrasonic pulses and listens through an array of tiny microphones, reading the Doppler signature of an insect's wings > That signal lets it tell a mosquito apart from a bee, then chase the target down and intercept it mid-air with propellers The company is backed by YC, and the founder previously engineered guidance and navigation systems for missiles. It's a legitimate project. They believe 10 drones could clear an entire square kilometre, cutting the cost of mosquito control by 100x So far though, the only public demo (below) was killing a moth in an enclosed room. Whether it works on a mosquito in the wild is the real test ahead

Microsoft's AI can now detect cancer from a $10 tissue sample. For context, every time tumor cells are tested, doctors create a basic microscope slide to study tissue up close. These slides show cell shapes and structures, but they can't reveal which immune cells are actually fighting the cancer. That deeper picture is critical for knowing if a patient will respond to immunotherapy... But the advanced imaging needed costs THOUSANDS. So Microsoft built GigaTIME -- an AI system that generates advanced imaging from the cheap slides hospitals already collect. The system was trained on 40 million cancer cells, then applied to over 14,000 patients across 51 hospitals spanning 24 cancer types. The AI found over 1,200 hidden connections between immune cell behavior and tumor growth that researchers couldn't find before... because the data simply didn't exist at this scale. When validated against 10,000 additional patients from a completely separate database, the results held up. The model is now open source, so any hospital worldwide can use it on samples they already have. I think this is one of the most impactful AI papers I've seen this year!

Meta is planning to power its AI data centers with solar energy beamed from space. If it works, solar farms could produce power 24/7 without batteries or backup generators. The company behind it all is Overview Energy -- they want to launch 1,000 satellites into orbit, 22,000 miles above the equator, where sunlight is constant. For context, Meta's data centers used over 18,000 gigawatt-hours of electricity last year. Enough to power 1.7 million American homes for a year. Each satellite collects solar energy, converts it into a wide beam of near-infrared light, and aims it at existing solar farms on the ground. The farms convert the light into electricity, just like they do with sunlight. Unlike high-power lasers or microwave beams, this infrared light is safe enough to stare directly into. Solar farms normally sit idle at night, so this system fixes that... from space. Really fascinating tech.

A typical post picks up 273 interactions against 596K followers, an engagement rate of 0.046%. Measured over 8 original posts, its engagement rate beats 57% of 3,774 tracked accounts of a similar size, which puts it in the middle of its size range rather than at either end. Posts are seen about 45K times each, and 0.601% of those impressions turn into an interaction.

- What is Rowan Cheung's engagement rate on X?
- Rowan Cheung (@rowancheung) has an engagement rate of 0.046%, based on the median interactions across 8 original posts from the last 30 days against 596,491 followers. Replies, reposts and quote-posts of other people are excluded from that sample.
- Is that a good engagement rate?
- At 0.046%, Rowan Cheung sits above the 25th percentile of the 36,521 accounts in this comparison. Those comparison accounts are all large ones, because our scanning cadence is weighted towards big accounts, so this is a ranking among peers of similar scale rather than a ranking across X.
- Does @rowancheung have real engagement?
- Its engagement rate beats 57% of the tracked X accounts closest to it in follower count (3,774 accounts), which puts it in the middle of its size range group. Ranking inside a size band matters because engagement rate falls as accounts grow, so a raw rate would mostly re-measure the follower count. It is a starting point for a look at follower quality, not a verdict on it.
- When does @rowancheung post?
- Most posts go out around 15:00 UTC, and Monday is its busiest day, at roughly 1.17 posts per day across the measured window.
