I really disagree with this statement. Language places heavy constraints on what can and cannot be expressed in poetry more than prose does. If poetry represents human emotion, then it should be easy to translate poetry to another language, but it’s not. Try using the same form of a poem and translate to another language and see if it has the same emotive effect - it’s really difficult to do so.
Poetry seems to express emotions because its constraints has limits on what can be conveyed effectively. As far as I understand, rhymes and meters used in poetry are more of mnemonic techniques from non-literate culture, like a check-sum or error correction mechanism. In post-literate culture, it’s merely a word play.
Maybe I just don’t like poetry.
If by this you mean "rhymes and meters", then perhaps. But, there is a whole world of interesting poetry unconstrained by such concerns. The form is significantly less constrained than prose - so much so that when prose does not conform to certain standards, readers often wonder if it is not too "poetic" to be considered prose.
In fact, poetic language is described as "the fullest possible language" where poets "pack the absolute maximum of meaning (in every sense of the word) into every part of the poem." This density of meaning and the ability to use language in unconventional ways actually expands the expressive possibilities in poetry beyond what is typically found in prose.

I dwell in Possibility – (466)
By Emily Dickinson
I dwell in Possibility –
A fairer House than Prose –
More numerous of Windows –
Superior – for Doors –
Of Chambers as the Cedars –
Impregnable of eye –
And for an everlasting Roof
The Gambrels of the Sky –
Of Visitors – the fairest –
For Occupation – This –
The spreading wide my narrow Hands
To gather Paradise –
At the same time, however, I feel like this kind of catastrophizing about the end art has happened so many times before (e.g., with the invention of photography, the rise of abstract art, or the emergence of digital art tools).
Each time, artists have adapted, found new ways to express themselves, and pushed the boundaries of creativity. AI might change the landscape of art (it certainly will), but it's unlikely to spell its end. Instead, it could (it certainly will) become a new tool for artists to explore and expand their creative horizons, much like how digital tools have been integrated into many artistic practices today.
