My talk clashed with queues for sandwiches and it was completely unclear as to whether I should be talking as the previous speaker was still chatting with people.
I decided to turn it into a conversation where I shared my concerns that the tensions involved in mixed-paradigms were untenable.
Technical leaders have to master both paradigms but the direction of travel is entirely towards immutability and FP.
There was a bit of back and forth but I didn't hear really convincing arguments that the thesis is wrong. Which is reassuring.
