Dave,
I wouldn’t worry about entering a chatbot next year, yet. This year, replacing NTFS with Node.JS, is not even on the books yet! That is good news for any contestant that did not make it into the final round. Places in the final round may start opening up last minute.
So these remarks are not intended to humiliate or criticize anyone. Node.JS bills itself as lightweight. Running message-mode simply may not work through ActiveX for the largest chatbot contestants designed to run on NTFS.
Microsoft has said, “Support for ancient protocols like ActiveX is being cut” and the hype that ActiveX is being sandboxed is false. In any case, it will be technically interesting to watch this year. The best of luck this year to all contestants, developers and contest officials!
