Whilst it may be off-topic slightly, from the above web page, that has
a link to the web page cited below, I think the laws below, are quite
astute...
"Wirth's law: Software gets slower more quickly than hardware gets faster."
- https://en.wikipedia.org/wiki/List_of_eponymous_laws
(which links to https://en.wikipedia.org/wiki/Wirth%27s_law
whence
"Gates's law ("The speed of software halves every 18 months") is an
anonymously coined variant on Wirth's law, its name referencing Bill
Gates, co-founder of Microsoft. It is an observation that the speed of
commercial software generally slows by 50% every 18 months, thereby
negating all the benefits of Moore's law. This could occur for a variety
of reasons: feature creep, code cruft, developer laziness, lack of
funding, forced updates, forced porting (to a newer OS or to support a
new technology) or a management turnover whose design philosophy does
not coincide with the previous manager.
May's law, named after David May, is a variant stating: "Software
efficiency halves every 18 months, compensating Moore's law". "
- see Sturgeon's Law, below)
and, especially,
"Andy and Bill's law describes how, when a computer chip is released,
new software will be released to use up all of its power. Named for Andy
Grove, then CEO of Intel, and Bill Gates, then CEO of Microsoft."
and, why are these laws, so true?
Because
"Sturgeon's law: "Ninety percent of everything is crud." Derived from a
quote by science fiction author Theodore Sturgeon (1918–1985)."
