Isn’t English already pretty simple as languages go?

A lot of these answers are working towards the idea of having consistent grapheme (letter or letter combo) to sound (phoneme) relationships. ie the letter ‘a’ would always represent the same sound, and that sound would always be represented by the letter ‘a’. This is called ideal phonemic orthography.

English has whatever the opposite of phonemic orthography is; depending on your accent, the letter ‘a’ has about 7 sounds the most common being ‘o’ as in ‘what’. It’s extremely unhelpful when teaching kids to read English.

Languages seem to pick up a lot of cruft over time as they grow, absorb loanwords and just change because language, so you usually only move towards phonemic orthography with some deliberate act, usually by the government.

An example might be Indonesia really wanting a national language to tie a very diverse population together after the second world war. I think they still have a government department who makes pronouncements about the language. The result of this is you could learn to correctly pronounce Indonesian in about 10 minutes, and read an Indonesian newspaper to a native speaker and it would be almost entirely intelligible to them even though you didn’t know the meaning of what you were reading.

Go read 1984 sometime. It includes a blueprint for “simplifying” English.

eliminate silent letters from all words

Not all letters are silent in all varieties of English (initial wh in some words, for instance).

make it so no letters share sounds

That sounds nice. Whose sound are you going to pick since not all are pronounced the same in all varieties of English, and how are you going to convince them to go along with it?

exampel

Wouldn’t eksampəl or ekzampəl be better? Speaking of, how would you handle things that are voiced in some contexts but not others? Would spelling differ? What about the noun present and the verb present? Would their spellings change?

The whole idea is nice on the surface, but has a ton of problems. Choosing one variety of English to be the prestige version and example is going to alienate others and probably just end up fracturing the language. I also don’t necessarily like that we’d lose the ability to figure out a word’s meanings by its parts if we know something about it from spelling (think words coming from Latin where I might be able to piece together what it means even if I’ve never seen the word itself) since the spellings would all likely change.

Ultimately, due to a number of problems, I wouldn’t change English; I should rather have people move toward a global lingua franca designed for the purpose, but all of those have their own issues as well.

Remove the letter “c”.

space, face, place etc. replace with “s” as it makes the “s” sound

score, scum etc. replace with “k” as it makes the “k” sound

Also what is the point of the letter “q” if it’s only followed by “u”, make the letter “q” mean “qu” to save space.

replace “ph” with “f”.

raplace instances or “y” where it makes the same sound as “i” with “i”.

Ie. the famous Bakunin quote: “In antiquity slaves were, in all honesty called slaves. In the middle ages, they took the name of serfs. Nowadays they are called wage earners.” ~ Mikhail Bakunin

would become “In antiqiti slaves were, in all honesti, kalled slaves. In the middle ages, they took the name of serfs. Nowadays they are kalled wage earners.”
