C is cool, asm is cool too.
The rest? Sometimes I thing as there is less hardware knowledge by programmers
each of those tries to re-invent the wheel  but without in depth knowledge,
resulting an a bunch of silly 'languages', that will change in every new release.
That will never be secure...
And why all that code? US got to the moon and back with less power than a Raspberry PI version 1

 
A Pi Pico has hundreds of times more compute power. Maybe thousands.
For $7.50.

Pi Pico is more powerful than the onboard computer.  But there were
also mainframes in ground support center.  Pico can perform more integer
instructions per second than those mainframes, but has less memory.
And mainframes had fast mass storage (drums and a disk farm).
Raspberry PI version 1 has more memory and SD-card has more bandwidth
than several mainframe disks.  OTOH I would avoid SD-card in mission
critical operations, so probably two Raspberries (two for reliablilty,
ground support mainframes also run in redundant configuration) with
external USB SSD discs...

I have 2 Pi4 Raspberries, one with 4 GB RAM and one with 8 GB RAM,
each with a 4 TB Toshiba harddisk.
SDcard for the OS to boot from, on one raspi normally that Toshiba sleeps
on the other it runs 24/7 recording 6 security cams, that one has a cooling fan.
There is Sitecom USB hub in between on each raspi, much more is connected to those raspberries,
for example RTL_SDR sticks for receiving RF stuff, use as spectrum analyzer,
receives outside weather station, can receive stereo FM, AM, SSB.
anything from about 20 MHz to 1.6 GHz,
an audio USB stick (mike), GPS (on the raspi serial port), Huawei 4G USB stick for internet access
IR camera on the GPIO, air pressure and magnetic compass on the GPIO, more...
Been running fine for years, all on a UPS.
Have a few more older raspoberries, one also running 24/7 as server for some stuff.
I do make backups from the SDcards to harddisk at times.
I seem to have stopped backing up to optical media as my 1000 disk box was full,
and the PC with disk burner is mostly off these days.
