Concept

Progressive enhancement vs graceful degradation

Similar approaches (for performance)

Pjax more granular and more obtrusive

Turbolinks Rails specific, less granular

Should I use it?

Enterprise, down to earth apps

Caring about users with old browsers

Much simpler than modern Javascript hell

Conclusion

Good choice for progressive enhancement

More granular than turbolinks, less obtrusive than pjax

Solves real problems

Relatively well documented

Could be tough to sell (not mainstream)

Thank you!
