Qt6 efforts to be efficient on both low level HW and on high level HW,
which is impossible w/o c++ backend
noone care about making web developers happy (besides web developers
themselves :) )
Flutter rather compete with Java-based apps, where it will gains from
performance perspective, but..again, c++ support in Flutter is still not
even close to production
And UI development in Flutter splitted up between platforms eliminating all
of the efforts to create single codebase
