How do you know if this isn&#x27;t March 2000 all over again.<p>A tech bubble would look different than in 2000 because companies didn&#x27;t go public the same numbers as last time. That blunts the impact a bit. But it also hides the impact. If VCs go into panic mode you won&#x27;t know about it until start ups start failing in high numbers from running out of runway.
