I guess I can't agree that people are largely lazy. We just have so much imagination, we can think of a lot of different things to do with the time we have! We have to make choices, and those will be based on personal combinations of talents and resources. Some will choose carving precious stones into intricate shapes, others will choose highly mathematical descriptions of 3-dimensional structures. If the two of them start sharing knowledge, they may make something really cool neither of them could have alone... and with neither of them truly understanding the nitty-gritty details of how the other's area of expertise operates!
Rather than laziness, think of it as the inevitable void between two worlds of expertise! They are experts in things you know nothing about, and vice-versa. Maybe there's no way to bridge the gap, but how will you ever know if you don't approach the other with respect?
Laziness is not a "bad" word. We might like to delve into our passion like some kind of craft but even with that, we try to be efficient and "cut corners" so we can be more efficient.
laziness hides in the details.
I guess I'm not sure what you mean by laziness, then. Maybe Laziness with a capital "L" is showing complete disinterest in everything that does not immediately and obviously produce value to the Lazy person, while laziness with a lower-case "l" is just the initial deer-in-the-headlights frozen response to a wide variety of possible details to which one might pay attention. That kind of lazy can certainly last a while! I tried to do all kinds of fun (to me) analyses of hashing methods before I ever gave it up. Once I realized it was a deeper swamp than I cared to get into, I decided to let those experts do their work while I come here and have fun with the ever-increasing world of steem-y ideas! I never really did look into exactly how the altcoin ledgers actually work... although I may get around to it, eventually. Or if possible, I'll take the "lazy" way out and ask someone who really understands it already to explain it while I sit with a dumb but fascinated expression on my face!
