FYI: 'Hilbert Walked so the Clay Mathematics Institute Could Run. The problems shaping modern mathematics' by Dr. E. J. Lamb,

https://blogs.scientificamerican.com/roots-of-unity/hilbert-walked-so-the-clay-mathematics-institute-could-run/.

In her article, Dr. Lamb believes that Hilbert's 10th is "clearly" solved. And that the Riemann Hypothesis, the central subproblem of Hilbert's 8th Problem, is "clearly" open.

I strongly disagree with her that Hilbert's 10th Problem is "clearly solved" since speculation (random and undirected or unintelligent endless solution searches of some DEs via an algorithm) is not proof! And therefore, I strongly believe Hilbert's 10th Problem is clearly open and is currently being investigated.

Moreover, I strongly believe the Riemann Hypothesis is clearly closed since Re(z) = 1/2 is clearly optimum for all primes and for all nontrivial zeros (z or zeta zeros) of Riemann Zeta Function and since the nth prime exists if only if the nth zeta zero exists...

Clearly,
