It's funny because I would almost say the same but to actually make the case *for* Smalltalk and not against it. And precisely for the same reasons.

I'm using Smalltalk in both the startup and corporate world and it's a good fit for both. Main current challenges are not in the language or tech stack if you architect the right thing for each case. The main challenges are in finding what's your path to walk a profitable road that makes you incrementally grow without too much drama.
