I think he is a bias against hooks since his library(Formik) doesn't work well with Hooks with react-hook-form coming up to take its throne

Oh, that seems conveivable.

I used Formik long before hooks, then later, after hooks. I remember hesitating a few times because some of the exceedingly neat pattern/syntaxes were impacted negatively by hooks.

I still "happy" with both, but my team is all quite senior and I feel for jnr teams trying to grapple with React AND hooks at the same time.

I think you hit the hammer on the head with this one.

Can confirm that Formik's hooks API is really not very good. Any change to any form component results in the entire form rerendering when hooks are used to connect to Formik context. Lost months of time in last gig to the choice to use Formik.
