Eric Kim’s 513‑kg rack‑pull has tipped into what platform researchers call a “runaway virality loop”: a spectacle so novel that it keeps re‑triggering engagement algorithms, stoking fresh memes, inspiring copy‑cats, and spawning controversy‑fuelled debates faster than the cycle can cool.  Because each of those elements — algorithm design, human psychology, and a built‑in sequel (the teased 525 kg attempt) — feeds the others, the clip still accelerates weeks after first posting, and the data show no natural ceiling in sight.  Below is a step‑by‑step look at the mechanisms turning this lift into social media’s latest runaway train.

1.  The spark: an impossible‑looking feat that anyone can remix

1.1  Numbers that shatter the “possible” frame

1.2  Built‑for‑meme visuals

2.  Algorithmic kerosene

2.1  Watch‑time loops on YouTube

2.2  Share‑rate weighting on TikTok

2.3  Negativity & controversy as engagement fuel

3.  Human psychology & meme economics

4.  Self‑reinforcing feedback loops

These stages iterate; SSRC researchers warn that adaptive algorithms and human behavior form “unpredictable feedback spirals” that are hard to throttle once momentum builds. 

5.  Structural reasons this train keeps picking up speed

5.1  A scheduled sequel

Kim’s blog now hosts a live countdown to a 525 kg attempt (24 Jun 2025), guaranteeing another surge of appointment viewing. 

5.2  Cross‑niche amplification

Crypto and tech influencers share the lift as a “proof‑of‑work” metaphor, expanding the audience beyond powerlifting. 

5.3  Influencer flywheel

Data show 84 % of marketers plan cross‑niche influencer partnerships in 2025 because they compound reach — exactly the behaviour emerging as strength coaches, philosophers and finance creators all weigh in. 

5.4  Meme culture’s undefeated track record

Marketing‑Dive’s long‑form review labels memes the “best force multiplier” in modern campaigns; as long as #GravityIsCancelled gags evolve, the algorithm keeps resurfacing the source clip. 

6.  What to watch next (and why it matters)

Bottom line

When a once‑in‑a‑lifetime spectacle collides with share‑heavy algorithms, negativity‑biased human nature, and a built‑in sequel hook, you get a runaway train: every skeptical tweet, stitched TikTok and reactive podcast carves a new track that loops back to the original video.  Unless that scaffold of algorithms, hype and human curiosity changes overnight, the locomotive will keep accelerating—right up to (and probably past) the 525 kg mark.  🚂💥
