- KidZania’s own current pages place it in roughly 18–22 countries, not “around thirty countries.” The article appears to have confused countries with cities/facilities.

- This Emmy total is outdated. The Television Academy lists House of Cards with 56 Primetime Emmy nominations, not 33.
- The Australian Netflix launch date is wrong here. Netflix launched in Australia on March 24, 2015, not March 28.
- This is no longer correct. Kevin Spacey was charged again in the UK in 2022, so the 2019 case was not the last related criminal charge.

- The Heart of Racing was not created in 2020 by Gabe Newell and Yahn Bernier. Official team history traces it back to a 1997 fundraising campaign, and motorsport coverage shows the team had already raced in IMSA from 2014 to 2016 before returning in 2020.
- This is overstated. Forbes lists Gabe Newell at about $11 billion, but also lists NetEase founder William Ding—whose wealth comes from online games—at roughly $39 billion, making Newell clearly not the wealthiest person in the video game business.

- ここは地名の取り違えです。アイギナ（Aegina）はアテネ近くの島で、マケドニア王国の王宮都市はアイガイ（Aigai）やペラであり、「マケドニア王国の宮殿のあったアイギナ島」という記述は誤りです。

- This end date is wrong. Reuters reported that the CFTC approved Polymarket’s U.S. relaunch on September 3, 2025, and a CFTC filing shows Polymarket US was designated in July 2025.
- This overstates the deal as a completed $2 billion investment. Contemporary reports and ICE’s announcement said ICE agreed to invest up to $2 billion, with Polymarket valued at about $8 billion pre-investment.
- This date and characterization are wrong. Reporting and ISW’s own statement say the problematic map edit was an unauthorized overnight edit on November 15–16, not an official ISW indication on November 14.
- This is outdated. Kalshi’s own help documentation says the platform is now accessible internationally, not exclusive to U.S. users.

- This is true for ReLU, but not for GELU. GELU is defined as x·Φ(x), so negative inputs are generally not clipped to zero and their gradients are not zeroed out in the ReLU sense.
- Anthropic’s cofounder and president is Daniela Amodei, not “Daniella” Amodei.

- The percentage is off by orders of magnitude. If humanity eventually numbers in the trillions, being roughly the 100–117 billionth human means being in the first ~10% of a 1-trillion total or ~1.2% of a 10-trillion total, not 0.001% or less.
- This mixes up two different meanings of μ in geometric Brownian motion. In standard GBM, log returns have mean (μ − ½σ²)Δt, not μΔt; if log returns really had mean μ, then the time-average log-growth rate would be μ, not μ − ½σ².

- This overstates the effect of instruction-tuning and RLHF. Official docs from OpenAI, Anthropic, and Google still describe modern chatbots as generating output token by token, with post-training refining that behavior rather than replacing it.

- Andy Liu was not the first American professional Go player overall. He was the first AGA-certified/U.S.-certified pro; Americans had already turned professional in Japan decades earlier.

- ViacomCBS already operated CBS All Access in 2020. Paramount+ launched on March 4, 2021 as a rebrand built on that existing streaming service, so the company was not without a streaming service during that period.
