I think it is about as hard as it ever was. The tricky part is learning to think through problems in a certain way, when you have that it doesn't matter much whether you're reading hexdumps and slinging low-level code on a 68k chip or clicking about in Godot and watching videos about clicking.

Crapping out code that does the thing was never the hard part, the hard part is reading the crap someone did and changing it. There are tradeoffs here, perhaps you might invest in modeling up front and use more or less formal methods, or you're just great at executing code over and over very fast with small adjustments and interpreting the result. Either way you'll eventually produce something robust that someone else can change reasonably fast when needed.

The additions to Java and C# are a lot about functional programming concepts, and we've had those since forever way back in the sixties. Map/reduce/filter are old concepts, and every loop is just recursion with some degree of veiling, it's not a big thing whether you piece it together in assembly or Scheme, typing it out isn't where you'll spend most of your time. That'll be reading it once it's no longer yesterday that you wrote it.

If I were to invent a 10x-meganinja-dev-superpower-tool it would be focused on static and execution analysis, with strong extendability in a simple DSL or programming language, and decent visualisation API:s. It would not be 'type here to spin the wheels and see what code drops out', that part is solved many times over already, in Wordpress, JAXB oriented CRM and so on. The ability to confidently implement change in a large, complex system is enabled by deterministic immediate analysis and visualisation.

Then there are the soft skills. While you're doing it you need to keep bosses and "stakeholders" happy and make sure they do not start worrying about the things you do. So you need to communicate reliably and clearly, in a language they understand, which is commonly pictures with simple words they use a lot every day and little arrows that bring the message together. Whether you use this or that mainstream programming language will not matter at all in this.
