This is only a realistic expectation for the single person who needs that hammer.

Otherwise we'll all individually be burning power via GPUs to reinvent the wheel thousands of times.

Also, look at the level of effort to maintain any bespoke machine. Assembly lines with interchangeable parts were a big deal for a reason. That follows with software via standard libraries and APIs. If you reinvent your software wheel every time, we'll all have careers trying to fix the deluge of slop that has been generated.
