I didnt say you shouldnt use a pick I said that fingerstyle and slap are basic techniques for bass. You can use a pick, I also used it but now I dont because I like playing with fingers. Any technique is welcome but bassics first. And that "I can play you recordings I made with a pick, and you wouldn't be able to tell those from the ones where I'm playing finger style". You can do everything with todays technology but thats not the point. Pick should sound like pick and fingers like fingers. I mean you can just take a guitar, use an octaver and set your amp or whatever to sound like you are using a bass.
