Parting thoughts
• Take-home messages from CIS 1001
– CIS is a growing field entering its golden age
• Physical world will be increasingly driven by computers and
information technology
• Increased importance of virtual and augmented reality world
– There is no free lunch
• Work hard
– Get good GPA
– Broaden your skills and perspective
• Make smart choices
– Get internships
– Do undergraduate research
– Open a startup
• Use resources available to you

Parting thoughts
• Web is the biggest knowledge source
– It contains all known wisdom, it is there for taking, use it for your advantage
– It can be a great time sink, there are many dead ends
