  9. The Trouble with “Platforms” Scientists’ creativity often exceeds pre-baked capabilities.

    
 Desire to go under the hood What if you want to access data that isn’t included? 
 Data catalog is determined by provider, not users

 Desire to go under the hood What if you want to access data that isn’t included? 
 Data catalog is determined by provider, not users Platforms are “single instance”: 
 Fear of lock-in, possibility platform will disappear
