I have a hunch that Dark won't generalise well. It might be good for making simple data-backed web applications. But a business of any nontrivial size has more than just simple data-backed web applications.

Do you use Dark for part of your business, and traditional tech for the rest, in which case you now have the problem of integrating your traditional stuff with Dark's black-box infrastructure?

Or do you build an MVP on Dark, then migrate on to traditional tech when you grow, in which case you now have the problem of migrating your entire business?

Or do you bet that Dark will pull more rabbits out of their hat, and you won't need to migrate?

Or do you use micro service architectures where some of your services (eg ML training) runs on dedicated/specialized hardware and traditional event/request based business logic can be written more quickly and only moved to Dark incrementally?
