As long as managers have limited budgets and projects have deadlines, then tradeoffs will still have to be made.

Event sourcing is an extremely expensive design pattern to implement, and it's also very easy to get wrong. Implementing it tends to preclude junior developers from working on the project, makes it harder for database admins to understand the data, and it requires a lot of thought on how to structure the events.

So on a project with, say, a £20K budget, it might triple the cost. On a project that would take 4 weeks to implement with CRUD, it might take 3 months with event sourcing. You've got to justify that extra cost. It's better to let a BA decide what they will need, and by all means explain the pros and cons of different solutions.

But I don't for a second believe that every single project should now be using event sourcing instead of CRUD.
