Traveling, palming, carrying

[World-wide Fan]

I have watched basketball games in several countries from middle-school to pro level for about 40 years now. I have read on this forum that fans say "Nobody calls that anymore" about traveling, palming and carrying. I agree with the fans for the most part but it doesn't mean I like it. Palming and carrying require a lot of judgement and gray area but traveling is merely a case of counting the steps. There must be some reasonable limit to this concept of free-to-travel. I see players who are making a "layup" (I believe now we would call it a dunk) take three steps on a routine basis while holding the ball and four steps will be overlooked by most officials. Thirty years ago, the limit was two steps. How does the number of allowed steps get changed? Is it by some rule book or just "fan demand"? Will we soon see five steps allowed? Will dribbling become a thing of the past?
