I noticed I didn’t even finish my previous comment, oops.
I do understand the physics, I work in engineering. I also looked at the spell desctiption from 5e D&D, it reduces the weight by 8, so the reduced weight would still be about 1-2kg. Not exactly a bullet yet.
I don’t see anything that could be considered a “Youth bad” statement in that comment. It’s a complex issue, influenced by a myriad of factors.
For example, I could dissasemle and reassemble my first PC without any prior knowledge. I had to learn to use DOS to navigate the OS and get things done. I got a book from the library about it, and spent hours upon hours just learning about how the file structure, commands, programs, external media, etc. worked before I could do anything remotely useful.
Today a PC/tablet/phone is a black box, you have to actively WANT to tinker in order to learn such about how they work. And most big tech companies try to punish you for so much as trying to replace a battery yourself.
I suspect you are projecting some personal feelings onto a stranger’s comment.
