Sad that Rust advocates are not learning. This sort of comment is what drives people away from Rust. Stop ramming your stuff down other people's throats. Go build that exclusively Rust based Dropbox clone that outperforms Dropbox and show how well Rust performs in that situation.

Rust has trade-offs just like Go has trade-offs. Being honest about the deficiencies of ones chosen platform is a good thing, it helps to keep you sharp and to avoid problems associated with those deficiencies.

Besides having an over-zealous community that posts off-topic comments all over threads that have nothing to do with Rust, Rust has deficiencies too.

Note also that Dropbox is already using Rust in some places.
