This could / was definitely true in the 201x. When most of the world's developers 's wages hasn't gone up evenly, and cost / infrastructure performance was expensive.

But we continue to see cost / performance improving. Ignoring the Rails framework and Ruby VM both together has likely gotten 2x speed improvement. We will get 96 Core Graviton v3 or 128 Core Zen 4 EPYC. Cost / Core performance is coming down and will continue to do so at least until Zen 6.

Depending on your App, somewhere along the line it will surely lean towards Ruby Rails's flavour. Assuming you do value what Rails have to offer.

I am just waiting for fibre/ async ( or something similar ) to be built into Rails and Active Record, along with even faster RubyJIT.
