I suppose the reason I don't 'get' Redux is probably that I don't 'get' the problem it claims to solve. Redux developers seem to say their issue with prior frameworks was that it was difficult to understand where state changes came from. But that's just not an issue I've had in the apps I've built.
Maybe the apps I call 'thick client' really aren't? Then again, I've done a fair few gigs in this game, on lots of kinds of projects, so I'd expect by now to have the perspective to say which was which.
That experience also makes me a little stubborn. I've had a few exchanges like this, where people have reacted with incredulity. They remind me a little of the arguments I had convincing people to abandon 'semantic' CSS, or grouping templates and view logic into components. I think history was on my side, at least in those cases, so I no longer feel abashed to walk against the crowd.
