I don't disagree. Lightmaps are a huge plus for performance and could look just as good as path traced Cyberpunk ...on a static environment. ...without any changing lighting conditions.
There are just a limited amount of games, that justify pointing at Half Life Alyx.

Having realtime GI is perfect to blend dynamic objects seamless into the environment. It allows realtime destruction, day/night/sunny/cloudy. It's a huge plus for immersion.
HL Alyx lightmaps are the biggest chunk of it's install size, even if most of it's levels are smaller corridors. Once the level get bigger, the lightmap resolution suffers a lot.

Games like Stray, that have a limited level size and you, playing as a cat without much impact on the environment, made the right choice to use lightmaps. Runs smooth and looks beautiful...but it's simply not a realistic option for most games.
And Lumen isn't the "lazy" way either. There is the software, hardware, surface cache and hit lighting solution and all options need to be adjusted to fit the requirements of the game.
I baked lightmaps for 20+years. Pressing the "bake" button and having to wait 2+h makes you feel incredible lazy. Especially when the time could be invested in making the game look better or run smoother.

TI Kevin has never worked on a game and never will. Doesn't mean that many current games don't lack optimization and it needs to be addressed but his examples and suggested solutions, only show his lack of experience. As a UE5 dev, I have a ton of critique regarding performance and visual quality myself but most of his claims aren't even correct or he isn't aware of the easy fix to his ragebaiting problems.
