I used to watch anti griefer videos on yt long time ago and modded in particular. Back then i had 0 clue about minecraft mods and how to get them. Most mods that i remember seeing are industrial craft railcraft thaumcraft in magic packs and most importantly gregtech 1-4. The main things that caught my eye were tools that gregteh added: screwdriver, files, saws. I did not know what they were used for but they looked cool af and i never saw them before in any other mod.
When i started playing mc with mods, i did not know much mod names or what they did, i just sort of glued custom packs together from the popular mods on curseforge. And guess what, gregtech was not there so i never actually found it until i googled after. 2018? i installed gregtech for the first time? I played and was so annoyed that all ores were “messed up” and other mods’ recipes too. I went into creative and shat myself when i saw the list of items gregtech5 added XD
I did not touch gregtech for another year as i classified it as an abomination from an illegal chinese website. 
After all that i was getting real bored with minecraft and mods so i started making my own for fun experiments and searching for unique mods out there…
You can guess what happens next, i installed gregtech5 again. Played in a custom pack as always and i had the coolest memories after watching some russian guides on the internet and finally getting something done (steam age). I don’t remember why i stopped but i did for some time and i lost that world i had.
Being sad that i lost my modpack and survival world i installed GTNH. That shit got me hooked like cocaine. I played too much and the quests were just too rewarding to complete. I stopped playing GTNH because it was consuming too much time and mental health + it was getting very grindy.
Well after GTNH i googled gregtech once again and started playing GT6. I was getting used to it and slowly realizing that this was the best mod. I was always a bit sad when i could not find machines from gt5 and below as i though that gt6 was missing content, when in reality, the machines did exist, just in a different form or multiblock.
That’s pretty much how i met grugtech.
