to be even more pedantic, hawking radiation isn't exactly created by gravity

In theory it’s created by the singularity boundary.

Related, I posted a paper on William Sidis earlier today where he explored the idea of a black hole before they were theorized or discovered: https://www.sidis.net/animate.pdf

furthermore, so far in universe (after big bang), nothing is really created, only transformed.

and (depending how time actually works) transformed also may be wrong, rather, everything simply is and time is our hallucination of reality

This does not compute in my mind, energy transfer (in some form) it is observed phenomena (my understanding (primitive) of time is energy transfer), even on quantum level we can measure it, what am I missing ?

You aren’t missing anything. He’s playing definitional word games, a common pastime of philosophers.

Dark energy is adding energy to the universe (mechanism unknown).

How does expansion of universe increases total energy ?

If anything seems like due to dark energy total energy dissipation per area is increasing until death of universe.

It takes work to separate two masses from each other (increasing gravitational potential energy). The universe is not just expanding, which might possibly be understood in an energy conserving way if the rate of expansion is slowing, but it is expanding at an ever increasing rate. Ergo enter guy is being dumped into the universe from some repository/field/whatever that we don’t understand. That’s what Dark Energy is.
