Everything is a field..and excitations in those fields.

I liked it. Would have been even better if he'd talked about the way energy is exchanged between quantized fields .. in 'quanta' (surprise!) .. not really particles at all ..

Quanta
Physics (Plural of Quantum)

    Definition: The plural of quantum, representing the minimum discrete amount of any physical property (such as energy or matter) involved in an interaction.

Examples: A photon is a single quantum of light, and electrons within an atom exist at quantized, discrete energy levels rather than a continuous range.

AI (?) ..
"The electron is considered the quantum of the electron-positron field. This classification means that electrons are not just particles but are also viewed as spatially extended bundles of field energy within this quantized material field."

Within an atom the quantized (electron) field is quantized into discrete energy levels .

Fun fact.. electrons were formed shortly after the Big Bang, no new electrons have been created since that time.

"not just particles" = also particles.
It's why Feynman diagrams are useful.

You can go further .. the 'particle' is always a particle .. introduces a pilot wave .. where that comes from and where it goes is unexplained.

"The de Broglie–Bohm theory, also known as the pilot wave theory, Bohmian mechanics, and the causal interpretation,[1] is an interpretation of quantum mechanics that postulates that, in addition to the wave function, a particle possesses a definite position at all times, even when unobserved."

There's a reason pilot-wave theory isn't the widely accepted interpretation. It actually has to posit an extra something we cannot observe. We cannot observe any wave while it acts as a particle, nor vice versa.
