AI has been improving dramatically since at least GPT-1 in 2017
GPT-1 was introduced in 2018, not 2017.
Full reasoning
This sentence dates GPT-1 incorrectly. OpenAI’s own announcement for the original GPT paper, “Improving language understanding with unsupervised learning,” is dated June 11, 2018. That is the GPT-1 release/publication, so referring to "GPT-1 in 2017" is a one-year date error.

The various WEO lines are World Energy Organization predictions for how quickly solar power will get deployed.
"WEO" does not stand for "World Energy Organization." It is the IEA’s "World Energy Outlook" report series.
Full reasoning
This expands the acronym incorrectly. On the IEA’s official site, WEO is the World Energy Outlook, described as the International Energy Agency’s flagship report on global energy analysis and projections. The IEA itself is the International Energy Agency, not a "World Energy Organization." So the article misidentifies what the WEO lines represent.

The last technology, ramjets, reached its limit at about 3500 km/h, and there wasn’t the economic/regulatory will to develop anything better, so the record stands.
About 3,500 km/h is not the air-breathing speed record, and it is not where ramjet/scramjet technology topped out. NASA says the current air-breathing record is the X-43A scramjet at nearly Mach 10.
Full reasoning
This sentence misstates the speed-record history.
NASA says the current world speed record for an air-breathing vehicle was set by the X-43A scramjet at nearly Mach 10 (about 7,000 mph, roughly 11,000 km/h) in 2004. NASA also says the previous air-breathing record was held by a ramjet-powered missile at a little over Mach 5. So ramjet/scramjet technology did not top out at about 3,500 km/h.
If the article meant a speed around 3,500 km/h, that is much closer to the SR-71 record. But NASA describes the SR-71 as the fastest crewed air-breathing vehicle at a little over Mach 3, i.e. a different category from "ramjets reached their limit." In short: the stated limit and record-holder are mismatched to the historical record.
