How to transfer a token on the ETH blockchain?
you can also write your own key generator using web3.py (https://github.com/ethereum/web3.py, see this part of the docs https://web3py.readthedocs.io/en/latest/web3.eth.account.html#creating-a-private-key)

MAIAN Smart Contract auditing
I understand from literally the only other thread about this on the internet (https://github.com/ethereum/web3.py/issues/879) that web3 removed 'KeepAliveRPCProvider' from newer versions. Is there a fix for this or is this tool obsolete now?

After heavy consideration and research I’ve decided not to spend a bunch of money on a bootcamp. So where to start?
There's also Github where many people have posted open source projects such as this: https://github.com/ethereum/web3.py

for a beginner
True but there is a decent amount of support for Python when it comes to Web3 (Web3.py for example). Plus, Python is a great starting language anyway

A very confused guy needs an advice on how to start
Another thing you might consider is web3.py. It might not be as useful as javascript libraries (web3/ethers), depending on what you plan to build, but the concepts are all the same and, again, you can leverage existing python knowledge.

Native Android SDKs for EVM?
In the meantime, one thing that might be helpful for Android developers is updating the document and/or providing the workaround. If an Android developer follows the documentation, an app won't work. A note along the lines of "web3j for Android is down until further notice", "join the discord for the android workaround", ... might be helpful. There have been some hints (eg 1, 2) about workarounds setup and use, but as far as we can tell, web3j for android is currently broken. It appears that there might be a workaround for most, basic Android web3j functionality, even with v4.8.8-android. We'll try the discord.

Any Smart Contract/Abi to Front-End Code Generator?
Just to add: there is also web3j (https://github.com/web3j/web3j) for the Java people. You can use Maven/Gradle and it generates stubs (classes) which use can use to call the Smart Contracts on any EVM chain. And it is type-safe (as corresponding Java types are used for the Solidity types).

Does a library like web3j only work for the Ethereum network or does it work with any blockchain that uses JSON RPC?
I'm trying to build a mobile app on a blockchain and unsure if a library like web3j would work with all blockchains that use JSON RPC

Is there a clean neat way to interface with Ethereum nodes?
There really wasn’t as of about 2 years ago at least. I worked on a Clojure backend that integrated with Ethereum and went with Java interior using https://github.com/web3j/web3j which wasn’t too painful.
