Showerthoughts

A "Showerthought" is a simple term used to describe the thoughts that pop into your head while you're doing everyday things like taking a shower, driving, or just daydreaming. The most popular seem to be lighthearted clever little truths, hidden in daily life.
Here are some examples to inspire your own showerthoughts:
- Both “200” and “160” are 2 minutes in microwave math
- When you’re a kid, you don’t realize you’re also watching your mom and dad grow up.
- More dreams have been destroyed by alarm clocks than anything else
Rules
- All posts must be showerthoughts
- The entire showerthought must be in the title
- No politics
- If your topic is in a grey area, please phrase it to emphasize the fascinating aspects, not the dramatic aspects. You can do this by avoiding overly politicized terms such as "capitalism" and "communism". If you must make comparisons, you can say something is different without saying something is better/worse.
- A good place for politics is c/politicaldiscussion
- Posts must be original/unique
- Adhere to Lemmy's Code of Conduct and the TOS
If you made it this far, showerthoughts is accepting new mods. This community is generally tame so its not a lot of work, but having a few more mods would help reports get addressed a little sooner.
Whats it like to be a mod? Reports just show up as messages in your Lemmy inbox, and if a different mod has already addressed the report, the message goes away and you never worry about it.

This is the right response - RTO is much worse for the climate than GenAI.
So I'm not saying RTO is worse than AI or vice versa. But do you have any data to back up that statement. I've been seeing nothing but news about AI data centers being an absolute nightmare for the planet. And even more so when corrupt politicians let then be built in places that already have trouble with maintaining normal water levels.
I get both are bad for the environment.
Editie: thanks for all the sources everyone. TIL
Proof was during COVID:
Well, real quick, my drive to the office is ~10 miles. My car gets ~3.1 miles/kwh. So let's say I use 3 KWH per trip, two trips a day, makes it 6KWH. A typical LLM request uses 0.0015KWH of electricity, so my single day commute in my car uses ~4000 LLM queries worth of electricity.
Yeah RTO is way worse, even for an EV that gets 91MPGe.
The thing is: those AI datacenters are used for a lot of things, LLM's usage amount to about 3% of usage, the rest is for stuff like image analysis, facial recognition, market analysis, recommendation services for streaming platforms and so on. And even the water usage is not really the big ticket item:
The issue of placement of data centers is another discussion, and i agree with you that placing data centers in locations that are not able to support them is bullshit. But people seem to simply not realize that everything we do has a cost. The US energy system uses 58 trillion gallons of water in withdrawals each year. ChatGPT use about 360 million liters/year, which comes down to 0.006% of Americas water usage / year. An average american household uses about 160 gallons of water / day; ChatGPT requests use about 20-50 ml/request. If you want to save water, go vegan or fix water pipes.
I'm on my phone so I can't fully crunch the numbers, but I took a few minutes to poke around and I think I found the stats to put both of these in perspective.

So yikes and without a doubt unsustainable energy usage, but comparing this to wikis article on COVID environmental impacts

My napkin math says that we would need ~532,407,407 AI queries to match the 2020 work for home drop, but unfortunately, Chat GPT alone is estimating 2.5 billion prompts, daily.
I started writing this assuming the opposite was true but unfortunately AI is a bigger environmental impact than an RTO. Which is honestly shocking. I hope someone corrects my math and tells me it isn't this dire. Work from should be the norm, but AI is truly just a massive environmental burden.
you got an error in magnitude there: its 5.32*10¹⁴ requests, so 532 407 407 407 407 requests
(2.3 × billion tonnes)/(4.32 grams) 2.3 billion tonnes = 2.3 trillion kilos = 2.3 quadrillion grams ≈ 532 407 000 000 000 requests needed for equivalence to Covid CO2 drop ≈ 912 500 000 000 requests made per year calculator output below:
See what i mean? Stop ChatGPT, achieve 0,0017% of the reduction that Covid brought.
To put this into perspective: imagine smoking 4.32 grams of weed every day and imagine how that would add up.
its more like 0.0017% of 4.32grams of weed, see my response above
