Yes, the space semantics of lazy evaluation is difficult to learn, particularly when coming from fully-strict languages, or languages with little support for lazy programming. Many other programming techniques face similar barriers: e.g. memoization, concurrency or logic programming result in similar brain twisting -- yet can be suprisingly useful. So I argue that programmers shouldn't be scared of technology -- embracing and learning new techniques can only improve your practice.
