tldr: venus is probably the worst choice.
venus is actually one of the most difficult to dismantle compared to mercury it has the following disadvantages:
- gravity:higher gravity on venus, means more energy is needed to launch mined material into space. on mercury a magnetic railgun powered by solar panels (that close to the sun) can more easily do it.
- atmosphere/climate:venus's atmosphere is thick, blocking most solar energy from reaching the surface. making solar a difficult power source. the rain on venus is so acidic almost noting survives on its surface for very long. where mercury has no atmosphere. meaning no friction, no hazardous weather etc. the fricture of venus' thick atmosphere would also be a huge detrimental force in lauching anything back up into space.
- surface temperature:venus has a much higher surface temperature than mercury, due to its runaway greenhouse effect. so high infact (up to 400*C) that most electronics will simply not operate. we would need to invent new cesium based electronics to operate anything on venus. Where mercury's day side is hot, its night side is actually very cold. ideal for operating electronics. and supercooling any magnets needed to operate a space launching railgun.
- available materials:mercury has large deposits of silicium on its surface, which can be used to locally product solar cells to operate machinery, factories and panels to power the dyson swarm. mercury also has a metalic core, which would be used to construct swarm segements, and electronics. where venus also has these materials (we think) its mostly its corrosive atmosphere with sulphuric acid rains that make production there almost impossible.
other more accesible targets:many asteroids in the asteroid belt between mars and jupiter would proably be mining targets sooner than venus is, simply because low gravity would make it easy to access, mine and launch towards the dyson swarm. some even have completely exposed metalic cores, could be moved into near earth orbit, or lunar orbit, and mined with more easy close to home.
this will be actually probably the first space mining industry's to develop, most people think blue origin and spacex final goal is space trips. but their final goal is probably space asteroid mining. capturing one of those metalic exposed asteroids and mining it, would make any company that achieves it an instant trillion dollar company. and it can probably me done with remotely controlled, or ai controlled space drones. within the next 50-100 years.

Friedman Dyson proposed an actual sphere. But in practice the sphere would be very difficult to keep in orbit. A small imbalance and it would destabilize and fall into the sun.
Swarms are much more easily executable.
They are not the same thing.

You're assuming all the materials are useful. While infact you need metals. Luckily mercury has an iron core. And we were talking Dyson sphere not swarm. A swarm would be much easier, as it requires much less material, much less stabilisation. And you can construct it a segment at a time.
A Dyson swarm at 0.1 au would also be very toasty.

Ye I've read papers with the math on this.
If just a few milimeters thick, you would still atleast need mercury and Venus. Remember the sun is hot, so you can't go to far in. You'd think getting a lower energy output star would help, but brown dwarves and red dwarves have unstable ejections and radiate making them unsuitable.

You'd need to dismantle a few planets to make a Dyson sphere.

Wouldnt it be cool, if product like Facebook, instead of focussing on adds and selling you stuff, would actively help people detect early stages of depression, lonely ness and actively work to help you get better before it gets worse.
Or expose people that have grown complacent to the things they need to be titulated to make changes in their life that would better their lives. Such as a move for education. A new job, ending a broken relationship. Reconnecting with old friends and such.
You know, put the social back in social media. Instead of the hyper consumerist brainwashing.
Aaah if only.

I like to think they're different in the sense that automation is the brain and mechanisation is the muscle. They do compliment eachother. And they are both forms of "industrialisation"

You could argue that AI is actually part of automation because it is "automated statistics"

The singularityi isn't real. Why? Because it's a bad description of the concept.
Knowledge expands at an exponential rate. This means that knowledge begets knowledge and discoveries follow eachother at increasingly shorter time frames. The speed of discovery is accelerating.
It is however not instant.
But! There will be a time somewhere in the future. Where knowledge moves at such a pace that humans will no longer be able to keep up with all the new discoveries being made in their fields. Simply because there are to many and there's not enough time.

microsoft te already beating google. Their income streams are more diversified. It has a huge stable client base (and has had so for 30 years)
Msft won't beat google at search. But then that's googles only "one trick pony." Google isn't beating Microsoft in business hardware, business software. Os etc etc etc!
If Google search gets displaced tomorrow the company loses all it's interest. If big gets replaced Microsoft will keep selling windows, SQL server, office etc etc etc.

Reply to [Discussion] If ML is based on data generated by humans, can it truly outperform humans? by groman434
Yes. First of all the ai can learn from all humans not just one. And the end result could be an ai with the knowledge and skills of 4 billion people. Which would ofcourse outperform anyone on the planet simply because no person can do it all...
But then ai has also been used already to advance mathematics. Solving previously unsolved mathematical problems.
Here's an example:
