If I tell you that clay is better for your next project then you don't know enough. Am I right or wrong - should you invest a lot of money into clay equipment, and time into learning to use clay? You need to make a decision based on what others say about the advantages of clay - maybe clay isn't better, maybe it is better but not by enough to be worth learning. If this is just for fun maybe you say you want to learn clay so you spend months learning to do it, but if this is for a job your really wants some confidence that clay is worth learning before investing your time to learn it.
Well if my day job is building stuff and it’s the reason I picked this career and it seems companies pay $$$$, give great benefits, and lets me take 2-4+ week vacations wherever I want if I’m good at it, and going to work is great because everyone gives you the fun problems knowing very well you know your shit…
Yes, it's worth learning a little about clay. Maybe I'll even enjoy it.
(And I know you’re trying to make an example, but I have already looked into clay a bunch of times. Clay just doesn't have the material properties that my projects tend to need. It'd be like learning COBOL expecting to build front-end apps.)
