> I have implemented language VMs and garbage collectors where I needed to work at the level of raw bytes and manual memory management
Fair enough, and I guess I'm forced to agree a little. However, if the one true language already existed, the VM/GC problem wouldn't have to be solved twice. Somebody had to write the first assembler in machine code, too.
I've written a (Hans Boehm style) GC of my own, and I admit that wouldn't fit with what I had in mind either, but working with raw bytes is a solvable problem in almost any level of programming language as a few library functions. All the batch or command line utilities, GUI applications, back end server modules, and most of the one-off exploratory programs could fit in a single elegant language.
> I like static types for decent-sized programs, but I also use config files and other "data languages" where that would be more frustrating than anything.
Again I agree, but (to me) this has a solution. I could be very content with a statically typed language with a single variant type for when you need to handle JSON-ish type dynamic variables or hierarchical data. I think dynamic and static typing can coexist very nicely in one language.
> Even if there was a single language that was perfect for me for all of the code I write, I don't expect that that language would be perfect for others, and I don't think those people are wrong.
I did caveat this was for single person programs and that different people would make different choices. I think my point was just that, having looked at languages from Icon to Prolog to SQL to Scheme to Ocaml to Rust to C++ and a lot of others, I think there is a point in the high-D trade space where I would be content to live and breath for almost every programming problem.
I've never gotten anyone else to agree, but I think it's an interesting exercise to fill in the details. I mean, computers are so much malleable than real world tools - you could have a single thing which handles screws, nails, rivets, and bolts effectively.
