السيرة
تخرج متكاف من MIT في 1969 بدرجتي بكالوريوس علوم, واحدة في الهندسة الكهربائية والأخرى في الإدارة من MIT Sloan School of Management. ثم مضى إلى هارڤرد للدراسة العليا, حيث حصل على ماجستير العلوم في 1970.
وبينما كان يعمل على رسالة الدكتوراه في فهم الحاسب, أخذ متكاف وظيفة مع MIT's Project MAC after Harvard refused to let him be responsible for connecting the school to the brand-new Arpanet. At MIT's Project MAC, Metcalfe was responsible for building some of the hardware that would link MIT's minicomputers with the Arpanet. Metcalfe was so enamored with Arpanet, he made it the topic of his doctoral dissertation. However, Harvard flunked him. His inspiration for a new dissertation came while working at Xerox PARC where he read a paper about the ALOHA network at the University of Hawaii. He identified and fixed some of the bugs in the AlohaNet model and made his analysis part of a revised thesis, which finally earned him his Harvard PhD in 1973.

Outside of his technical achievements, Metcalfe is perhaps best known for his 1995 prediction that the internet would suffer a catastrophic collapse the following year; he promised to eat his words if it did not. During his key note speech at the Sixth WWW International Conference in 1997, he took a printed copy of his column that predicted the collapse, put it in a blender with some liquid and then consumed the pulpy mass. This was after he tried to eat his words in the form of a very large cake, but the audience strongly protested; the cake was quite good [بحاجة لمصدر] and was eaten by some of the audience after the speech.
During an event where he talked about predictions at the Eighth International World Wide Web Conference in 1999, a participant asked: what is the bet?. He stated that there was no bet as he was not ready to eat another column.
Metcalfe is also known for his harsh criticism of open source software, and Linux in particular, predicting that the latter would be obliterated after Microsoft released Windows 2000:
- The Open Source Movement's ideology is utopian balderdash [... that] reminds me of communism. [...] Linux [is like] organic software grown in utopia by spiritualists [...] When they bring organic fruit to market, you pay extra for small apples with open sores – the Open Sores Movement. When [Windows 2000] gets here, goodbye Linux.
