Definitely not: Anything where latency matters and there are real performance memory constraints. GC is a show stopper for anything high performamce or databases etc. Doing it the hard way: anything with a complex domain e.g geospatial applications where you have an exponential explosion of different logics for different types of shapes or modelling medical ontologies. You can write anything in any language the issue is if you're taking the path of least resistance to do it and how much risk you're exposing yourself too with variable skill levels of developers doing it. E.g see all the frankenpython implementations kicking around banks and Instagram to use the "simple" language that turns into something much more complex and brittle.
