endowed with intelligence or consciousness by master craftsmen. The study of logic and formal reasoning from antiquity to the present led directly to the invention of the <a href="/wiki/Computer" title="Computer">programmable digital computer</a> in the 1940s, a machine based on the abstract essence of mathematical reasoning. This device and the ideas behind it inspired a handful of scientists to begin seriously discussing the possibility of building an <a href="/wiki/Electronic_brain" class="mw-redirect" title="Electronic brain">electronic brain</a>. The field of AI research was founded at a <a href="/wiki/Dartmouth_workshop" title="Dartmouth workshop">workshop</a> held on the campus of <a href="/wiki/Dartmouth_College" title="Dartmouth College">Dartmouth College</a> during the summer of 1956.<a href="#cite_note-FOOTNOTEKaplanHaenlein2018-1">[1]</a> Attendees of the workshop became the leaders of AI research for decades. Many of them predicted that machines as intelligent as humans would exist within a generation. The <a href="/wiki/DARPA" title="DARPA">U.S. government</a> provided millions of dollars to make this vision come true.<a href="#cite_note-FOOTNOTENewquist1994143–156-2">[2]</a> Eventually, it became obvious that researchers had grossly underestimated the difficulty of the project.<a href="#cite_note-FOOTNOTENewquist1994144–152-3">[3]</a> In 1974, criticism from <a href="/wiki/James_Lighthill" title="James Lighthill">James Lighthill</a> and pressure from the U.S. Congress led the <a href="/wiki/DARPA" title="DARPA">U.S.</a> and <a href="/wiki/British_Government" class="mw-redirect" title="British Government">British Governments</a> to stop funding undirected research into artificial intelligence. Seven years later, a visionary initiative by the <a href="/wiki/Japanese_Government" class="mw-redirect" title="Japanese Government">Japanese Government</a> and the success of <a href="/wiki/Expert_system" title="Expert system">expert systems</a> reinvigorated investment in AI and by the late 80s the industry had grown into the billions of dollars. However, investors' enthusiasm waned in the 1990s and the field was criticized in the press and avoided by industry (a period known as the "<a href="/wiki/AI_Winter" class="mw-redirect" title="AI Winter">AI Winter</a>"). Nevertheless, research and funding continued to grow under other names. In the early 2000s, <a href="/wiki/Machine_learning" title="Machine learning">machine learning</a> was applied to a wide range of problems in academia and industry. The success was due to the availability of powerful computer hardware, the collection of immense data sets and the application of solid mathematical methods.
