Explore a 29-minute conference talk that delves into the fascinating parallels between Ruby and Smalltalk programming languages. Learn about the groundbreaking developments at Xerox PARC in the early 1970s, where modern computing concepts like GUIs, WYSIWYG, and IDEs were born. Discover how Alan Kay's work on Smalltalk in 1972 laid foundations that would later be reflected in Ruby's design. Gain insights into the historical context of Smalltalk's creation and understand how Ruby independently evolved to embrace similar concepts. Examine the implications of these historical connections for Ruby's future development and evolution in programming language design.
