My washing machine does a lot better job than I could. My oven is much more reliable at heating than I am at building campfires. My computer is much quicker at maths than I am. My TV is cheaper than going to the theatre.

Automation is great when it works well, we just forget about it when it does, so we generally only recognise the bad.

Perhaps, but your dishwasher is probably not be better than a person dedicated to washing dishes.

My dishwasher often leaves dirty spots and stripes, which would easily be noticed and removed by a dedicated person.

It's orders of magnitude cheaper though, and most people would accept a >90% good enough job for <1% of the price.

Also I recommend the Technology Connections videos on how dishwashers work. Most people are probably not using them correctly for optimal results.

TLDW: Stop using detergent packs, start using the pre-wash bin.

I saw this but had a huge box of soap packs. So I started putting one in the prewash thingy and two more soap packs in the main section.

Now it cleans shockingly well.

Try using multiple soap packets and rinse-aid. Works wonders.

Good thing we have mostly automated production of soap packs, so they’re cheap, plentiful, and almost as good as the handmade ones our caveman ancestors used

Mine doesn't.
