Athletes are going faster, higher and longer and as a result the technology that measures their feats at the Olympics needs to keep up

I think the real reason they need better technology is because athletes are NOT really going faster, higher and longer.
They want to keep getting new world records, so they have to get more precise measure so that one can beat the record by 0.001 second...

The other reason is, as you say :

With 0.02 seconds splitting the 3 fastest runners in the 100m, you know that's just a bit too close.

They need better technology to determine who is the winner. Great. But, again, this is not related to athletes going faster, higher and longer...
