Radical approach - they flip the whole thing upside down. The biggest challange is not new language or ide per-se imho - but detachment from git, this has implications ie. it seems open-source hostile (you can't use it for open-source code, or am I wrong?); what about libraries?<p>Technically very interesting.<p>Practically I'm not sure it'll fly, at any complexity project development means in big part playing around locally before pushing ideas up. On dark platform the code seems to be in compiled = deployed state only, or am I wrong? What about documentation, how is testing done, benchmarking, integration tests, if the system goes crazy, is there a way to actually stop it? What about recovery from backups? Reverting to past history code? After reverting is the new code still available so it can be fixed before next deployment?<p>The scope they're claiming is gigantic, they must be taking compromises somewhere. There's no way is all unicorns and rainbows.<p>However if they manage to execute it well, the potential is huge - they can create marketplace for libraries/services, they can become appstore+github+aws in one for execution-ready solutions (libraries, services etc), which could be huge.<p>Wolfram does something similar. Salesforce as well. Dark seems similar but for webdev, it's like serverless/lambda v10.
