Totally agree. I've been in this industry since 2001 and never, ever had a performance problem which couldn't be solved with just thinking what your code is actually doing. The bottleneck has been always the database, or the network, etc. The only problem I've had with threaded languages is running out of threads/processes due to making external API network requests, etc, but you learn to not block threads by using jobs, etc. And worst case, more hardware has been always cheaper than more developers due to less productive languages (hello Go! :wink: :wink:).
You are not Google.
