The fundamental difference between the valuations today and those in the 2000 is that most tech companies are actually operationally solvent. That is not true for all of them, but if a crisis hit valuations and investors lost all confidence, companies with operational solvency will care very little and will not close down. There is something similar to a bubble that plagues the sector and its those B2C companies that insistently build themselves to capture users and get their value from selling out to the big boys without ever making a decent profit.
