It’s a valid point and that’s the biggest question when it comes to the medium to long term business plan. Those R&D costs are an important part of it. My point is that since runtime is profitable there is a lot more runway to figure out how to tweak R&D spend in such a way that it becomes a viable business for the long term.
There are a lot of questions that they need to answer to get to pure profitability but they are also the fastest growing company on a MAU number in history with a product that you can see has a chance at become profitable from all sides. They may fail or become sidelined but the hyperbole and lack of critical discussion here is disappointing.
