I spent my childhood with a desktop (mid 90s to mid 2000s) then I had gaming notebooks until 2018 or so, except for a 3 year period in beginning of the 2010s.
A gaming laptop (or even a mid-weight laptop with an eGPU) is always a compromise (in both directions).
A "gaming desktop" can generally do so much more than just gaming. I did video editing and encoding on my gaming laptop, you can make it work, it's slow and the heat noise can get annoying (versus a desktop that's possible to make quite even under load).
And with some ML video stuff like Topaz Video (*) even a powerful desktop can struggle, I can't image using Topaz video on any laptop. Especially any tasks with 4K using complex algorithms beat my poor desktop to pulp (5800X, 3080, 64 GB, not the latest and greatest, but no slouch).
(*) I've successfully upscaled older video footage (586x320) from mid the 2000 by 4x along with X4 frame interpolation without it looking overly fake and being pretty decent quality. You can even do complex scenes like public events as long as you have source 720p footage. It's like magic.
Also large storage is a pain with laptops. You really need a fast SSD with at least 2TB (it's also good to have a secondary SSD) and another 10 TB+ HDD storage. This type of setup is difficult with a laptop.
