IMO technique is a tool, nothing more, nothing less. If the music/your ideas require a higher level of technique, then yes, it is very important. If the music/your ideas dont require a high level of technique then no, its not of particular importance. For example, to execute Dream Theater bass parts (thinking instrumedley, metropolis part 1) with fluidity, a high level of technique and dexterity is required. Wheras with Jamiroquai tunes, a fantastic sense of groove is far more important than raw technical prowess.
