That’s why Apple makes the Air, 8gb is perfectly fine for that product. If one is making a pro product 8gb makes no sense considering it’s not upgradable.
Depends on the "pro" task... 8GB in Apple Silicon (in any M1, 2 or 3 regular, max or pro combo) is more than enough in my experience and opinion if you'll do music recording/live performance/production, etc. on your own or with a regular 3 to 5 piece band, light to mid 4K video work, light to mid 3D tasks wether for CAD, concepts, animation or simulations, definitely overkill for business suites and project management, and some light coding/development stuff.
There are lots of pro jobs that would benefit from a mobile rig with 16GB plus, especially if those jobs are "bring your own rig" positions or on-field jobs like recording a local orchestra at an impromptu location with an audio interface that handles more than 16 I/O setups plus a dedicated SSD drive and mixing desk, integrating with a pre-viz, pre or post-production team for AV or 3D projects... basically collaborative tasks on mid to large size projects.
If you need more than 32GB or 64GB, you are talking about integrating with big teams, networks, you are into running several virtual machines for software development, testing, debugging, and all sorts of niche and specialized stuff for large/plus sized projects or productions whether you work remote or on-site. You decide if desktop or laptop is your required tool.
That's why many here say "Hey, if you need to spend 200 bucks more on SSDs or RAM, you know you need it or not, and whether it's the right/required platform or not." It's never about "Apple is the bad guy and is abusing me. I wish their machines were less expensive."
Bus speeds, longevity of components and stuff like that, a pro will already know which brand and product tier is the right tool or not, and if it's priced according to a budget.
