>>11219878>Why should I do it? Obviously we can't answer that for you. If you dabbled in algebraic topology then you already know that pure maths won't be very relevant at your job unless you teach/research.
So do it if you like it. For instance, did you like the ideas behind homology, cohomology, Mayer-Vietoris, Ext/Tor functors, free resolutions, etc.? There's more where that came from.
There is another option which is getting into applied stuff like stochastic analysis and econometrics which may net you a job in the future if you need it.
Otherwise you should sit down and carefully think about what hobby skills do you want yourself to have in, say, 5 years. Do you want to play piano? Draw? Learn another language? Maths will eat time from some of your hobbiy, so prioritize.
