Ignoring the snark from other posters, there are a few things to consider.
First, there are bassists who have had successful solo careers like Steve Lawson, Michael Manring, and Victor Wooten, to name a few. However, they are very much in the minority and are all accomplished bassists who have the skill and experience to play in an ensemble, even if they often perform solo bass arrangements.
I don't know Lawson's background but every accomplished soloist I can think of started out playing in bands, mastering the bass in it's traditional role, and branched out into solo arrangements later in their career.
Also, all of the aforementioned solo artists are incredibly dedicated, skilled, and experienced musicians. It's not a matter of whether or not that's attainable, but more a commitment to the absolute daily grind required to master an instrument and reach the skill level required to do those kinds of performances. Most people, even experienced musicians, don't go that far.
Onto the bass itself, the first question would be: why? If you are already a bass player then it makes sense to spread your wings and explore the world of solo bass arrangements. But if your goal is to be a musician who performs as a solo artist then the bass guitar is a very odd choice. It's not designed to be a solo instrument, it's range is specifically tuned to accompany others in an ensemble, and the physics of the instrument make it quite demanding to produce quality solo arrangements.
If one were starting out with such a goal, tackling the piano or classical guitar would make more sense. It's like setting out to build a house with a wrench instead of a hammer. Sure, it's technically possible, but you are making the work orders of magnitude harder on yourself to reach the same goal.
