Yes! (at least for me). I'm building a gamified iOS keyboard (self employed), and I have to build an auto–corrective, predictive engine for it. That was a detour for my main target, but is part of the MVP of a keyboard (as we are in 2018, and it's expected by every user). The constraints of time and memory, really pushed me in revisiting a lot of data structures (mostly tries and DAWG), there is not much information out there, and not much libraries already build, so I have to get creative, read a few papers, tech blogs, etc and do it myself. So, from what I'm reading here, the moral of the story is, probably you will find joy pursuing your own interests, don't expect to find tech–challenges in your average job.
