OK, let's go over it then.
1. You chose a center for your sector manually before, and how many systems were in it. Unless the specific capital has some sort of sweeping, game-changing effect (unlikely, most it'll be is a minor bonus of some kind) this is just the AI adding planets to a sector for you and undoubtedly doing it exactly as well (lol) as it does everything else. What's that, the sector AI thinks it needs your living metal for farming? Sounds great.
2. I'm sure this will be completely different from focusing on energy and minerals or science. It won't be options like "balance between energy and minerals" or "focus on unity". Sure. What's going to actually happen is you're going to want to make a science sector, but you can't choose the capital you want with good science bonuses because there's like 3-4 good science planets that are just outside of it's reach, so the numbers will balance out to exactly what they were before the update either due to a sub-par capital or sub-par planets in the sector.
3. Auto budget is the only thing I acknowledged as different, but it's really just automating a process that you did manually before. Saves a few clicks, and that IS GOOD, but it's hardly game changing.
4. It is good to be able to choose what type of planet focus you want, but I don't see how that's really different from "just build alloy structures for alloy bonuses". Are we going to build farms then change it to a forge world bonus? I think not.
I'm not sure what he's about with governors and sectors. They already have bonuses to sectors. Governors have always had effects for whether they were on a planet or a sector. Is he talking about governors that have sector specific bonuses instead of planetary? Because I already hire/fire governors to get things I actually need often enough, thank you.
This is all just "AI automation options for stuff". I will be glad to have more options but it's not going to change the way anyone plays.
