I think the thing people have to understand is how fast the value proposition is changing. There is a lot of conversation about "plateauing" model performance, but the actual experience from the combination of the model and tooling changes is night and day in the last 3 months. It was beginning to be very useful with Claude 3.7 in the spring this year, but we have just gone through a step function change.

I was decomissioning some code and I made the mistake of asking for an "exhaustive" analysis of the areas I needed to remove. Sonnet 4.5 took 30 minutes looking around and compiling a detailed report on exactly what needed to be removed from this very very brownfield project and after I reviewed the report, it one shot the decommisioning of the code (in this case I was using CLaude in the Cursor tooling at work). It was overkill, but impressive how well it mapped all the ramifications in the code base by greping around.
