I don't think you're quite understanding the trick the parent comment is trying to tell you.

You press your finger on the sound icon, and just start sliding without waiting. It's one fluid gestural motion. Try it out. It takes the same effort as tapping a physical button but gives you more fine grained control. Yes, it's something new and different from the way you're used to, but give it a chance.

Sliding still does not a simple tap, with tactile feedback, equate.

I'm aware I can do this. It still drives me nuts - and I have to agree with eksemplar when I think it is simply a serious step backwards in design and should be an option, not forced like the 2018 models.

The lack of tactile feedback is huge.

Take a MacBook with the function keys, and one with the touchbar. Then adjust the brightness or volume on both at the same time and the hand that operates the touchbar gets “lost” so easily

Still more work than quickly tapping once or twice. With the slider I have to carefully slide to get the exact amount, all without any tactical feedback.

Tactile feedback? What for? You have visual and audio feedback. After all, you are trying to set volume or brightness to a specific level...

You can just tap and slide at once. (Without releasing your finger) Its actually faster than with old buttons.

How is tapping and sliding easier than pressing a button once?

You don't need to lift your finger, which takes time. Just shift your finger left/right a little bit.

But that’s not faster.

The old way: click, you’re done. The new way: click, hold finger, slide, and you’re done.

Like I said, it’s faster to go from 1 to 10, but 99% of the times I use it, I’m just changing the volume by 1.

Hell, it’s easier for my brain to just click 10 times than to watch where the damn slider is too.

Ah, you're comparing it to the old hardware keys. I see your point.

Another alternative is to simply flick the touch bar button.

you don't need to click and wait though, just tap and without lifting your finger immediately slide to adjust. If anything it's a super minor annoyance imo.
