Inevitably they get bored or the fad dies out, nothing is gained, but then people still excitedly go along with the next one every time as if they have no memory of the previous 1000 iterations.

Many of the people involved in the new fad don't have a memory of the previous 1000 iterations because they are different people. Many new people are joining the internet every day. Also be aware of the obvious-in-hindsight bias: anyone can point out fads after they've come and gone. It's not as easy confidently identifying the fads that are going on right now.

I can't work out what they mean by this.
