alt Hacker NewsUber has a history of blaming the tool - in Facebook fashion - rather than admitting their “talent” sucks and they didn’t hire on merit.
They used to blame Python a lot too - Python is slow compared to others but not so slow to matter that much, and you can build other services around it to handle certain work.
Facebook - who chose PHP - used to blame iOS/Obj-c as the reason they couldn’t build a decent Facebook native app in the early days (anyone remember Fastbook?)
I would take it with a grain of salt.
What concrete arguments are there to believe in your talent hypothesis instead of their tool hypothesis?
A couple more comments like this from you, and I'll be able to say, "cyanmoonx has a history of blaming the talent rather than bad tools". There being a history like that is neither an argument for nor against tools being bad. And also, don't forget that bad tools and bad talent don't rule each other out.
