Except you're talking to a former Nokia employee that knows enough about Symbian and J2ME, and had enough of Dalvik falsehoods regarding JVM implementation techniques on constrained devices.
Yes, I remember meeting many Nokia employees at that time (when there was a still a Nokia Symbian vs. iPhoneOS vs. Android race in progress) and they all seemed to be on the wrong planet when it came to developer mindset.
I distinclty remember Nokia trying to sell us on Qt app development... where apps were only actually able to run on like 2 devices out of their 100+ device portfolio. It was hillarious how misguided they were.
That's a really good point but thinking about it that way brings the decision to use Java at all into question. Clearly iOS/iPhones did great with ObjC in the same era.
"Java programming culture" outright would not work which was obvious to anyone trying to write fast code back then.
(I also wonder how many users are willing to trade off 15% of their battery time to developer java programming culture.)
