Kermit is still used in the embedded space, on modern platforms specifically for uboot.
zmodem can also be used in embedded spaces to retrieve files if the only interface is a serial port.

I care a lot more about outcomes than whether the person I'm talking to is "real" or not. If my bill gets corrected by an AI but not a person? I'll take the AI.
Think of the classic "is 0.002 cents the same as 0.002 dollars?" call - https://verizonmath.blogspot.com/ - I just tested, and chatGPT seems to understand the difference - so maybe this would be a case where the AI is better.
edit: to be clear I'm fine with labeling if that's desired, it's the "I want to talk to a real person" that I think is silly (and oddly similar to the "I want to talk to an American" that people also say).
You logic is sound ... maybe too sound.
Have AI already taken over HK comments.

What does a coal-fired power plant need that stuff for?
Presumably, they were measuring the level of coal (or other material) in a tank. Look up "ohmart radioactive level transmitter".
It looks as if this type of device is still sold today.

Afaik the problem is typically not hardware but software, since most server motherboards come with a bmc chip on it. Are you designing a motherboard? All i would ask for a bmc is root access. But now everyone (but the big players, who design their own motherboards) is basically stuck with a stupid embedded linux with shitty software that has half-backed features they don't even need, but now need to care about. When all you'd need would be a way to access a host serial console, read sensors, control boot sequence and perhaps re-flash the bios, ie most likely just basic interactions on serial interfaces.
> Are you designing a motherboard?
Yes, the team I work for designs server motherboards.
BMC security is what keeps me up at night. Firmware software quality is low, and often not up to date. I think openbmc does a good job in both respects.

We got into that when we started expecting servers to have VGA and PS/2 ports because an RS-232 console would not be very useful with a GUI.
Is there a modular standard for BMCs?
There are two standards for pluggable BMC's
- runbmc (https://www.opencompute.org/documents/ocp-runbmc-daughterboard-card-design-specification-v1-4-1-pdf)
- DC-SCM https://www.opencompute.org/documents/ocp-dc-scm-spec-rev-1-0-pdf

I do development on openbmc (https://github.com/openbmc/openbmc) which is an open source bmc implantation using bitbake, primarily targeted to aspeed, and nuvoton bmc chips.

1) Tail end of the year - its hard to get full time roles , The hiring definitely picks up after Jan 2nd week or so.
2) Try consulting/contracting - That space is still brimming w hiring. Much faster on-boarding /hiring.
2) Consulting makes sense, companies are less likely to hire in a downturn (because they want to avoid increasing ongoing cost). However,is still work to be done, and timelines to be made. A "one time" expense is easier to justify.
I would enjoy real world (apples to apples) comparison of the cost of cloud vs self hosting. There are many speculations and approximates, but some hard facts would go along way.

I was told in highschool that the major with the most job opportunities was petroleum engineer. I'd be hesitant to have kids make career defining choices based on data that can change on a whim.
My freshman year I was aiming to enter the engineering program, so I could be a petroleum engineer, for the reasons above.
I took an intro CS, and that changed everything.
I agree with you that you should be able to run whatever since in the end it’s just another computer, but the manufacturers believe otherwise since there’s “valuable IP” or whatever nonsense (insert rollseyes emoji here).
There are open specs like redfish but still doesn’t get to the heart of the matter.
AMI sells a bmc software stack, https://www.ami.com/megarac/ Intel and small manufacturer were unhappy, about always paying the ami tax. So intel created openbmc, as a hedge against ami's monopoly for small manufacturers. I have heard Openbmc has user from facebook, google, ibm, bytdance, and ali.
Dell owns their own stack in idrac, I have heard most of their systems are nuvoton based. I am suspect dell pays some big bucks to keep their systems at feature parity with the other options, and they view it as a an investment.
There are also silicon devices on the motherboard, that have drivers that are not able to be shared. So it not surprising that companies don't share source in a way that would be useful.
If you wanted a system that as a bmc that could be tested try the asrock-e3c246d4c, it looks like there are hobbyist, that have it running coreboot, and openbmc. (impressively)
