2️⃣ After I finished it I started playing around with Keras and scikit-learn to build a model of my guitar amplifier.
It took 72 hours of recording, 250+ hours of training, and 6 months of experimenting to conclude - ML algorithms like NN won't produce anything useful.
It reads and writes almost like the English language. You need a small amount of code to get a job done. You'll probably rewrite it at least 3 times.
2️⃣ 1st class citizen on cloud platforms
You don't want to deal with physical servers in a startup. You just want to run your app. Python has cloud SDK libraries, it runs on serverless platforms, it's used in ML services, a lot of examples in cloud docs are using Python.
