Which computer smarts less?

I've seen reports like this one by Ashley Turner for some years; smartphones are some people's first computers. I started using computers in this order: desktop computer (1998), laptop computer (2000), smartphone, tablet computer.

1. Some stages of telecommunication:

a. "Repeat this message to them when you meet them!"

b. "Give them this letter!"

c. "Pick up the phone (receiver)!"

d. "Did you get my text? "

e. "I think my phone is smart."

It's actually a computer with an antenna.

No computer or other artefact is smart.

f. "This looks like a computer."

According to Federica Laricchia , it seems that some 170 million tablet computers were sold in 2021. "Tablet sales in 2022 were down 5% from 2021, with a total of 150.8 million tablets shipped.", Jada Jones reported. We might be using 1 billion of them. Why do they keep making the least successful computers?

g. a computer with a battery and a larger screen

h. a computer for ergonomic and better organised telecommunication

These 4 types of computers are called "personal computers" here . Other authors seem to use this name only for the 2 types of computers with which we typically use the largest screens: desktop computers and laptop computers. It seems that we bought 340 million of these larger computers in 2021, out of which maybe 277 were laptop computers. Thomas Alsop reported that 286 million personal computers were bought in 2022.

It seems that we were using 1.5 billion personal computers in 2015 and 2 billion in 2019.

It seems we bought 1.2 billion smartphones in 2022. If we used 6.64 billion smartphones in 2022 and 6.37 billion in 2021, maybe 0.27 billion people started using a smartphone and 0.93 billion replaced their smartphones.

2. When would we replace the following 7 billion smartphones?

2.1 Heather Webb wrote : "The composition of phones varies depending on the brand, but an average materials list for a smartphone is: 25% silicon, 23% plastic, 20% iron, 14%, aluminium, 7% copper, 6% lead, 2% zinc, 1% tin, 1% nickel and 0.03% barium." If a smartphone weighs 200 grams on average, we use for it e.g. around:

2.1.1 50 grams of silicon

For 7 billion smartphones, 350 kt.

Silicon seems available as long as enough people mine for it using enough water and we recycle it quickly enough.

2.1.2 46 grams of plastic: 322 kt

We're producing a lot of plastic.

Akhlaqul Karomah wrote : "The main elements used to make plastics are cellulose, coal, natural gas, salt, and crude oil"

2.1.3 40 grams of iron: 280 kt

It seems that iron could last us at least until 2100. This seems a very short time, given that we've been using it for millennia. Are some people going to use iron from Australia, Canada, and the USA, while others from the other 7 main sources?

2.1.4 28 grams of aluminium: 196 kt

"bauxite reserves amounted to 31 billion dry metric tons" in 2022

We could extract bauxite until 2100 and use aluminium for an even longer time.

2.1.5 14 grams of copper: 98 kt

The global copper reserves are estimated at 880 Mt and could last us at least until 2060.

If we recycle some 30% of it, we could recycle 264 Mt in stage 1 (40 years), in stage 2 (12 years) we might recycle only 80 Mt, and in stage 3 (4 years) 24 Mt. It seems we could use copper until after 2080. It seems we have been using it for 11 millennia and it plays a role in humans and other beings, as other substances mentioned here do.

Mark P Mills warns us of a copper shortage starting in 2025.

2.1.6 12 grams of lead: 84 kt

"In 2022 , total global reserves of lead amounted to 85 million metric tons." "In 2022 , approximately 4.49 million metric tons of lead was extracted from mines worldwide." We could mine for lead until 2070. Its recycling seems efficient and costly .

It is used in the circuit boards . Fascinating as they are, electronic devices can be a short-lived fashion. Until what decade can we cooperate over the Internet?

2.1.7 4 grams of zinc: 28 kt

Total global reserves of zinc are estimated to be some 210 million metric tons. In 2022, the?total global mine production was approximately 13 million metric tons.?Are we going to mine all the zinc by 2040? We could use it until later to the extent (more than 30%) that we recycle it. We could recycle 63 Mt in stage 1 (5 years) and 19 Mt in stage 2 (2 years).

Without it, products made of iron will corrode faster.

2.1.8 2 grams of tin: 14 kt

"the world’s reported tin resources at the end of 2019 totalled some 15.4 Mt" "current demand levels can be supported for" 50 more years. 2070.

2.1.9 2 grams of nickel : 14 kt

"As of 2022 , the total global nickel reserves amounted to approximately 100 million metric tons." "The 2022?global nickel production?amounted to an estimated 3.3 million metric tons." Nickel can become hard to get by after 2050. If we recycle 80 of the 100 Mt in stage 1 (30 years), in stage 2 (24 years) we might recycle only 64 Mt, in stage 3 (20 years) 51 Mt, in stage 4 (15 years) 41 Mt, in stage 5 (12 years) 32 Mt, in stage 6 (10 years) 26 Mt, in stage 7 (8 years) 21 Mt, in stage 8 (6 years) 16 Mt, in stage 9 (5 years) 13 Mt, in stage 10 (4 years) 10 Mt, in stage 11 (3 years) 8 Mt, in stage 12 (2 years) 7 Mt, in stage 13 5 Mt, and in stage 14 4 Mt, which might last us a couple of years. This can add up to 110 years, but the situation is more complex.

We also use nickel to make stainless steel, which contains some 8% nickel . "the amount of stainless steel scrap currently being used reduces the energy required for stainless steel manufacture by around one-third over using 100% virgin materials." Have we planned on how to manage these materials and the necessary energy? We seem to recycle some 60% of steel.

Smartphones are computers with batteries.

2.2 We use e.g. these materials to make batteries:

2.2.1 It seems that we had 22.4 Mt of lithium in 2021, which could last us some 200 years.

2.2.2 It seems that the 330 Mt of graphite could last us some 300 years.

2.2.3 It seems that in 2021 we had reserves of 7.6 Mt of cobalt, which could last us until 2070.

"Battery technology and recycling alone will not save the electric mobility transition from future cobalt shortages " "the cobalt supply shortage appears inevitable in the short- to medium-term (during 2028-2033)"

We seem to recycle 25% of the cobalt used in some of the most developed economies.

It seems safer to rely on desktop computers. You can discuss with Sol Computing how to configure your computing environment.

It seems safer to rely on public transportation. We can talk about what changes you'd find useful. You can have Sol Transportation help you make them.

2.2.4 "In 2022 , the total global reserves of manganese were estimated at around 1.7 billion metric tons"

"The total global production volume of manganese in 2021 was 49.5 million metric tons."

It could last us until 2050.

2.3 It doesn't seem certain that we can replace the current 7 billion smartphones once.

I can see the costs of smartphones. They look like a luxury item made to milk people.

I find the Internet very useful. I wish we used it better than for many videos, mainly about fucking. Is life about more than dick dips and talking alone?

To help people communicate remotely, I would think more before acting. We gave people tiny hybrid devices before allowing larger computers to connect to the Internet over the air. Maybe it's more useful to provide capable desktop computers that help people achieve more and serve them longer.
