Personally I agree, but the world doesn't seem to. Their first project (https://sam.zeloof.xyz/first-ic/) was all the way back in 2018, and it doesn't seem like it changed all too much (yet), while since I read the first blog post in 2018, I also thought we would have reached a much more mature DIY ecosystem by now.
Don't get me wrong, I'm excited too about it, and can't wait to personally do some experiments as well, although not at the same scale. But I'm not sure it's world changing, at least until I've actually seen any changes :)
