Technology - What are the differences and similarities of the dot-com bubble and today's technology boom and how big is the chance that another crash might occur?

Abstract

In the 90ies computers and mobile phone became parts of people's everyday life. Technology companies grew extremely fast and many start-ups have been founded after 1995 and went public even though most of them have not been profitable at that time. At the end of 1999 investors started to sell their technology stocks, which ended in a crash of the so-called dot-com bubble in March 2000. Yet 18 years later, the technology sector is booming again and there are some signs of an overvaluation. Is the technology sector heading towards another bubble?
