Doesn't that happen everywhere? Sporting records don't usually change dramatically, but get better in small increments. The next world record for the 100m may only be a few hundredths of a second faster than the current record - it's extremely unlikely to be 2-3 whole seconds faster.
Same with science, once someone makes a breakthrough with a new theory, it takes years to investigate all the implications. Look at Darwin for example. There's not been a new 'Theory of Evolution' for over 150 years, but scientists have made many small breakthroughs in understanding the mechanisms - DNA and RNA for example - by which species change. Darwin only explained broadly 'why' they changed - now scientists are gradually finding out 'how'.
Maybe we just don't see new developments because they're incredibly complicated and don't emerge from laboratories or technical publications into our 'normal' day-to-day existence.
