“Not useful” —- one of those moments where you have to be able to adjust your views in the face of new evidence. Humans are so wedded to their beliefs that it can be agonising to let go. I have nothing but respect for people who admit they were wrong, though. I remained a skeptic for a long time, but 4.5 was enough to convince me to adopt for production code.

So far I updated from "meh, not useful" to "scary, not useful".

If it would be useful I would continue to use it, but at this point I would not use even if it would be free, not proprietary and not funding replacing me.
