In the 1980s, when Andreessen was in college, AI was a niche field and everyone thought it would never come true.

Judge whether, during Andreessen's college years (about 1989–1993; the claim says the 1980s), AI was a niche field and there was widespread skepticism that it would ever achieve its goals. 'Everyone thought' is read as broad prevailing skepticism, not literal unanimity. True: histories describe AI at that time as a small, marginal field in an 'AI winter', with low funding and broad doubt about its prospects. Mostly true: this holds for his college years, but the dating is slightly off (e.g. his college years were mostly in the early 1990s, not the 1980s), or optimistic factions still existed. Mixed: it holds for the late 1980s, but the earlier-1980s expert-systems boom (large commercial and government investment and hype) contradicts it for much of the decade. Mostly false: AI was a well-funded, prominent field with substantial optimism during the period, and only isolated skepticism existed. False: the evidence shows AI was mainstream and widely expected to succeed.

   “The second AI winter, which began around 1987 and lasted into the early 1990s, was different. This time, entire industries collapsed. Billions of dollars in private investment evaporated.”

   “The expert systems that had driven the 1980s boom turned out to be brittle, expensive to maintain, and impossible to scale.”

4. E4 Marc Andreessen Encyclopedia.com · 14 August 1995

   “After graduating from the University of Illinois with a bachelor of science degree in 1993, Andreessen took a job with Enterprise Integration Technologies, a producer of Internet security-enhancement products, in California.”

E4 shows Andreessen graduated from the University of Illinois in 1993, so his college years were mostly in the early 1990s rather than the 1980s. E1 dates the second AI winter from about 1987 into the early 1990s and describes the collapse of whole industries and the loss of billions in investment, which supports a downturn and broad doubt about AI during those years. E2 says the expert-systems boom drove the 1980s, which contradicts his "1980s" dating for most of that decade, and E3 says some research carried on through the winter. Under the criteria, this fits mostly true: the description holds for his actual college years, but the dating is somewhat off.
