Yesterday, one of my friends called me after a long time's silence. She told me their company laid off 120 people this week. Their stock option is garbage now. Each share is worthy more than $1 USD. She is not in the lay-off list but she is looking for a new job.
Sooner or later, IT industry will shrink and readjust itself. At that time, if we are laid off ... it means the whole sky collaps.
