The best tool is the best tool for the job. My php code was immaculate - import header, write your content, import footer. I wrote it all in a few hours, and I think my university is still using it today. One of my proudest moments was when a team member whose abilities I respected gushed over how easy my code was to work with

I haven't used it since.

I'm led to believe modern PHP has become pretty good. It's also never been the right tool for the job since then

Mojo sounds incredible - python is a beautifully consistent language, and I've written a shit load of it. I like it a lot. It's often not the right tool for the job, but mojo promises to turn it into something extraordinary that shores up its weaknesses... It's just promises so far though, I really hope they pan out

But always ask yourself - what's the right tool for the job?
