Not to mention that I don't walk around with that mirrorless camera in my pocket at almost all times.
My Z50 and kit lens fits in my pocket fine.
It takes 10x longer to setup, take, and post-process and is a hassle for many reasons, but the photo quality is extremely noticeably better.
Camera bodies will keep being updated. Glass is updated, but a lot more stable.
If I have a friend who wants to invest, say, $3,000 in a camera setup, I'd tell them to get a $1,000 body and $2,000 of lenses. A couple have thought they'd buy a $2,500 body and $500 lens, and I explained why they might be disappointed with that investment.
