When Facebook was hitting performance issues with PHP, they decided to rewrite the entire runtime instead of rewriting in a different language.

If Facebook with its billions decided it was cheaper to rewrite PHP, the cost/benefit analysis must favor optimizing current code than doing a rewrite

Facebook is Facebook. Slack isn't Facebook, and neither is every other business besides Facebook Facebook decided to rewrite PHP because the CBA worked out for Facebook - that doesn't mean the argument holds true by default for any other situation.
