I think this is an excellent point. That being said, there are some warm fuzzies that come by seeing my grad school research topic listed here as well (the ML for physics simulations topic). Just some validation that the area I'm spending time in could not only help my specific niche, but be broadly attractive to VC funding to help grow it. Not that I'm anywhere near being ready to build anything (or near graduation, for that matter) but the conversation about it being a possibility came up recently and maybe sometime in the far future it could be a reality.
