The complaints about the thickness are too much of an overreaction. Are any of you complaining actually gonna use this for its intended purpose?
Photo Editing - you are likely lugging around some expensive DSLR camera and lenses which are just as heavy or heavier.
Graphic design - You probably gonna keep it stationed on a desk most of time and occasionally bring it with you and I suspect people like you are not always gonna bring something like this to a coffee shop. You likely have a complimentary device like an iPad Air, MacBook Air or even just your iPhone for light use. So, even if you need to show in progress work to a client and make minor edits, you use your iPad. Heck, this is 2021, you share the project with the client using Adobe CCs roundtrip features. You don't even need to take a device with you anywhere. But you certainly will want those ports to connect up to high resolution monitors.
3D rendering - you don't mind this being a desktop replacement, when those fans kick in, you will be glad its thick enough for great air flow so you are not throttled and can keep working. You likely even have a Mac Pro or iMac too. Again, its likely gonna be stationary.
Audio production - As a DAW, this thing hardly ever leaves a studio anyway, but there is some portability if you take it to a club on Friday nights where you moonlight as a DJ. Hardly anything to complain about when you consider that its likely the only thing you are carrying with you, since if you are a DJ, the club already has its own turn tables and sound system. My sibling is a DJ and he lugs around an bulky old Toshiba (hopefully I can treat him to one of these) with heavy sound system equipment. A laptop weight is the least of his problems.
Video editing - again, this thing is gonna be sitting on a table or in an editing bay most of the time and for the rare times you take it out in the field, it will be mostly light work. No one is doing video production work in a wilderness or noisy city. You want to be in a quite space, no distractions, making sure you captured the audio, no distortions ability to think clearly.
Software development - its gonna be on a desk most of the time hooked up to three different displays, one in portrait the others in landscape - this thing ain't moving unless its an earth quake or you are going home for the holidays. Even then, you likely have complimentary devices as a developer that you use to augment it. So, if you are vacationing in Europe, you would take a MacBook Air to do light coding work while the family is out shopping. Heck, you will likely remote into the MacBook Pro M1 Max if you need to do anything major.
STEM - again, this thing is gonna be sitting in a lab on a desk most of the time.
Also, again, if you walk, take the train/bus to work, you put it your backpack, you are gonna have this on your desk for 8 hours of the day. The 2 hour commute you might carry this thing around for is not gonna break your back. Otherwise, there are other options you can choose from, but you are not gonna have your cake and eat it, too.
But, most of what I have already said so far are first world problems. Many folks carried around first gen Intel MacBook Pros and PowerBook G4 17 inch without complaint. I always remember sitting in a JFK terminal and seeing a guy with a broken leg killing time with a 17 in G4 in his laptop watching a movie. Never seemed to bother him.
What I hope is Apple just pushes the limit and reintroduce the 17 inch or even 18 or 19 inch version of the MacBook Pro.
