I’ve long thought the idea of “A Todo App” makes no sense because everyone works a little differently. That’s why apps like Pivotal Tracker are such garbage... they support too many use cases to do anything well.
The problem is if you try to make it configurable, you still have all the complexity behind the scenes. And your configuration UI recapitulates that hell.
So there is a need for someone to come in and start over with a more configurable foundation and maintain really serious software engineering discipline so that the base layer doesn’t get infected with individual business requirements (which will eventually be infinite).
I don’t envy Airtable trying to do this with a big client roster and huge scale. I think the problem would be easier solved in a smaller company with less pressure from investment timeline.
BUT if they’ve already solved the problem, or at least solved it to their satisfaction, then they will be fine and the platform can get as convoluted as they need to make their clients happy.
It’s only if there’s research remaining, core UI questions to be solved, that they’ll have a hard time competing with whomever comes to eat their lunch.
