No one is even thinking about trying to completely automate coding.
There's tons of "no code" solutions - but these are all just different versions of coding and programming languages - usually with GUIs and pictures instead of words.
There's more than 60,000 SWEs that work in my company. Amazon, Google, Apple, and MSFT could make >$10Bn/year each if they could automate coding.
The fact that none of them are even trying - when it sort of goes with their core businesses - should give you some indication that this is something unlikely to be automated any time soon.
The reason bricklaying ISN'T automated is probably because there's ONLY 59,000 bricklayers in the US (a $3B market), it's not generalizable, and even if it was - the cost to move a machine, set it up, and maintain it - it's hard to imagine massive cost savings - 50% seems generous.
If there were >1M bricklayers - and/or they made >$400k/year on average, the work was generalizable, and automating would bring huge cost-savings that could be captured - there would be a LOT more effort into automating bricklaying.
But none of these are true. How much of brick laying is generalizable (building a new house) vs custom (repairing some old wall with non-standard bricks)? I have no idea - but I'm guessing not a lot more than 50%. That's a $1.5B market. You'd be luck to cut the costs by 50% - that's maybe $750M.
It could easily cost more than than to automate bricklaying! Why even try?? No one is interested in investing in that risk / reward.
On the contrary - most of Radiology could be automated and most of it is generalizable. Since hospitals are monopolies and healthcare is a mess - you might be able to capture all the cost savings - which would be close to 100%!
Since there's ~35k Radiologists, and they're some of the highest paid workers in the world - there are a lot of efforts to actually automate this (and they're doing quite well).
If you think automating radiology is easier than building a hamburger-cooking robot, you're naive. If you think AGI is easier to achieve than building a tomato-harvesting machine, you're clueless.
There's just simply not hundreds of billions to be made automating cooking hamburgers and harvesting tomatoes more efficiently. And it's not easy to generalize and automate cooking or harvesting EVERYTHING. And even if there was, restaurants and groceries are commodities - not monopolies. You couldn't capture all the savings. A race to the bottom on prices would eventually just pass the savings on to the customer - not juice profits. That's not something you want to spend massive, risky R&D on. That's why we haven't automated cooking hamburgers and harvesting tomatoes. Not because it's harder than protein folding, fusion energy, or true AGI...
From another point of view - we've had machines that mop floors for decades - and there's still a lot of people employed to mop floors. Is this because mopping floors is incredibly complex and creative? No - it's because people who mop floors get paid minimum wage, and they do a lot of other things, too.
