Almost 20 years ago (!) I opined: "C is the New Assembly", suggesting that we had moved beyond the need to optimize things by writing assembly code. If I wrote the same article today, it might be "Hand-written Code is the New Assembly" https://redsweater.com/blog/278/c-is-the-new-assembly
C Is The New Assembly –

@danielpunkass Worked Bell Labs in 1980’s before breakup of AT&T. Learned Unix & C quickly after starting, took C with me when left to program IBM PC’s for rest of my career. Very useful for early PC’s with slow processors, could switch to Assembly from C at any time for asynch communication algorithms & the like that required all the speed the processor was capable of. Loved the language & the power it provided the programmer, of course no-one else could ever figure out how my programs worked 🙂
