Alphabet itself said on December 21, 2017 that Schmidt would transition "as of its next regular board meeting in January 2018" from executive chairman to technical advisor. In other words, he was still executive chairman through the end of 2017 and became technical advisor in January 2018, not 2017.

Alphabet's 2018 proxy statement confirms this, listing Schmidt as "Technical Advisor, Former Executive Chairman, Alphabet" and stating that he served as Executive Chairman ... from April 2011 to January 2018. Schmidt's own biography likewise says: "From 2018-2020, Eric served as the Technical Advisor to Alphabet" and "He was also the Executive Chairman of Alphabet from 2015-2018."

So the article's dates are inaccurate on both parts of the claim: his Alphabet executive-chairman tenure extended into 2018, and his technical-advisor role began in 2018, not 2017.

Official Rise and Rhodes Trust materials describe Rise as a global program, not one restricted to lower-income countries.

Rise's own press release for the first cohort says the application process called for talented people ages 15 to 17 "from around the world", and notes that applicants came from over 170 countries. The Rise Fellows page likewise shows fellows from countries including the United States, Canada, Australia, Spain, the United Kingdom, and many others, which directly contradicts the claim that the program is targeted only at students from lower-income countries.

So while the age range is broadly right, the article's limitation to "lower-income countries" is incorrect.

Official materials for the National Security Commission on Artificial Intelligence identify Eric Schmidt as Chair and Robert O. Work as Vice Chair.

The commission's final report lists the commission members with "Eric Schmidt — Chair" and "Robert Work — Vice Chair." A House hearing on the commission likewise introduced "Dr. Eric Schmidt, Chairman of the Commission" and "Hon. Robert Work, Vice Chairman."

So describing Schmidt and Work as having co-chaired the commission is inaccurate; the official titles were chair and vice chair.
