As a data point, 20% of the internet runs WordPress [1], think these people spent a lot of time thinking about architecture.

A lot of time the problem being solved is in fact simple enough and easy enough to solve without thinking about architecture, not everything is a hard problem - and there is nothing noble about solving things over and over.

The point I was disagreeing with was "Pick stacks as late as possible". If you have a large project by all means do that, if you're just building a REST API in microservice architecture, or you're building a blog or something that's fairly simple to model - you're perfectly fine picking a framework you like first.
