because idiots want it doesn’t make it a bad idea. With rusty’s new opcode budget rework it’s no more of a risk than any other opcode. 

 True, but this time around I need to be absolutely CONVINCED before I say Yes to any big change to Bitcoin like op_cat 

 op_cat is a small change, it just concats two values on the stack 

 it was only disabled because satoshi was concerned about DoS attacks, which rusty shown is easy to fix 

 this is an important topic. whats a good resource to really understand the implications of what's being proposed?  

 True to the idiots part, they are highly tarded 

 What does the OP_CAT change? 

 I have a feeling that’s why they are revving up how many nodes they’re all running
