I am so glad that people like Louis Rossmann[1], Electronics Repair School[2], NorthridgeFix[3] and countless others have worked to change that perception.
Chip-level repair SHOULD be the norm.
China has been the master at this stuff for a while with institutes like Wantong Training School, Shenzhen etc.
It is a real shame that much of this knowledge is either on Chinese or Russian Internet forums or buried in obscure and unsearchable YouTube videos.

DIY'ing this is something I would never trust myself with. There are people who do this day in and day out and I would trust them with it.
Searching for "bga soldered ram chip change laptop" on YouTube returns like thousands of results of people doing this.
Although I now realize how skewed my perception of microsoldering and other such skills because such skills seem to be extremely niche in the west.

It is fairly simple business to desolder the old BGA chip and replace with a new one.
There are specialized shops willing to do this around the world. This is especially common in third world countries, Eastern Europe, China etc.. There are people who would do this change for around 5-10 USD in India (as long as you can find the replacement yourself).
I am amazed at how many people on this forum think of this as some scary dark magic.

The 200GB one had a folder called .pad that was about 150GB and had nothing but null byte files in it.
Don't try to brag about something that doesn't exist please

I strongly believe sudo must not be installed on personal user systems. It's attack surface is far too large and that too for features no one other than enterprise is ever gonna use.
How many systems have sudo installed and how many of them are using sudoers config in LDAP or SSSD or the log collector or any of the stupid features like chroot etc.?

The code is open source and has been looked at by several people over the years.
It would be quite hard for the NSA to sneak in a backdoor but it is never out of the question.
However, the risk is so extremely minuscule when compared to other alternatives since they are not even open source.

I am unable to do https://python-type-challenges.zeabur.app/intermediate/calla...
I am doing
type SingleStringInput = Callable[[str], None]
EDIT:
I got the problem. You need a new line at the end since it seems as if it is concatenating my last line to the first line of the test.

Elon's swipe at Microsoft Teams is golden
As for where they learn it, there are tons of informal institutes, courses teaching people mobile/laptop repairing.
Although I will say, the people doing repairing in India have very little knowledge about basic electronics.
There are companies like Borneo (and other Chinese companies) selling schematics and laptop/phone specific repair/unlock guides doing much of the heavy lifting of distributing knowledge in this area.
As for what tools are involved etc. you can search "Learn Mobile Repairing" on YouTube and you'll get a lot of videos.
Here is a small list of people selling courses on mobile repairing in India alone:
