I would agree, I would also add that generally programmers today are not used to dealing with the memory limits of '80s computers. What is now considered an embedded device, back then was a desktop. My smartwatch likely has more memory than a PC Jr.
nodejs' main binary on my laptop is 44 MiB.
The Apollo Guidance Computer (AGC) we put a man on the Moon with could do 4 kilo instructions per second and 0.43 megaflops and had 2KB of RAM. Apple watch is roughly 900x as fast as the AGC while being being .67 x as large and less than 1% of the weight.
Vs the PC Jr, it's almost 2000x the size of an Apple watch and like 150x heavier.
In 2013 I bought Galaxy Gear which was one of the first smartwatches and even that one had 512 MB RAM. PC Jr. had a 64 KB RAM base in comparison.
And that is considered very affordable chip.
