Well, this punched a lot of TB's buttons - "bass is simpler than guitar" and "bassists are frustrated guitarists."
The thing is, both of these statements are SOMETIMES true. There are a lot of bands where teenage kids got together in a garage and the least capable guitarist got "demoted" to bass. There are people who took up bass because they had the notion (before learning to play) that it would be easy. Heck, my own daughter, home from college, declared over dinner that she would fill her summer free time by learning both bass and guitar. When she affirmed that she was serious, I gave her a first lesson on the basics of playing. She hasn't come back. It wasn't as simple as she assumed (or maybe I'm just an awful teacher, I don't know). And, a lot of bass parts are the simplest parts in rock and pop songs.
But only sometimes. I took up bass because I love the sound of the bass and what it does in a song, not because I couldn't cut it on guitar. I took up guitar later, because I wanted to better understand what guitarist's were doing and for songwriting. And, as I've posted before, what's simple is not the bass but the music that's often written for it. If you played the bass line - just the bass line - to U2's "With or Without You" on piano or guitar it would be very very simple to do. If you set out to play Pachelbel's Canon on bass (solo) it would be very difficult and require a high level of musicianship. What's simple or complex is not the instrument but the music you play on it. There are a lot of crappy guitarists churning out power chords while bassists compose melodic lines with groove.
Anyway, to the OP - if you have the money for a rig and the time to work on it, by all means, try bass. It's a great instrument. Moving to bass from guitar will be easier than if you were moving to it from flute or oboe or something. It still has strings and frets and you understand the role of an amplifier. But as someone else mentioned, it isn't the same instrument, any more than playing tuba is the same as trumpet or double bass is the same as violin. Some things you know from guitar will translate - others not. Focus on learning it as its own instrument and find its own voice in the music.
