Same in France - in the past you used to have enough time to finish filling your grocery bags while the transaction was being authorized. But for... maybe the last decade or so, transactions most often get authorized within a second of validating your PIN.

Plus now most shops have contact less card readers. Which is funny when you think about it, because it's the same speed / security than the swipe from 40 years ago, except limited to 20€.

I wouldn't say it's the same security - presumably the contactless chip is much harder to copy than the old magnetic stripe.

Contactless transactions generate a one-time use code, they're much more secure than your standard magnetic swipe.

No they just have different issues.
They both allow the card to be used when stolen. Magnetic band can be duplicated. Contact less allow people with a portable modified machine to request transaction without the owner knowing.
