Making Python (near infinitely) faster by using it as a glue language, and running all the computation outside Python :-P
Yeah what's wrong with that? I think this sounds amazing. It gives you all the fast prototyping and simplicity of Python, but once you hit that bottleneck all you have to do is bring in a ringer to replace key components with a faster language.
No need to use Golang or Rust from the start, no need for those resources until you absolutely need the speed improvement. Sounds like a dream to a lot of people who find it much easier to develop in Python.
Python is a rough language to be productive in. It's a great scratchpad, but dynamic typing, exceptions/poor error handling, and a horrifying deployment and dependency system make me reach for something like Go in any case where I need something to be even vaguely reliable.
The more ML I do, the more disappointed I get.
Ever tried gluing Go with either Python or JavaScript? I'm interested in learning what libraries are there to glue them and how complicated and slow they could be.
