Art is materially different from science and technology. Great art is known to emerge from limitations. Art is full of limitations that are self-imposed for that purpose, like the meter and rhyme in poetry, geometry and color in painting, etc. Art is primarily about processing and evoking emotions.
Science requires much more concentration on abstract thinking, loading a much larger context, if you will. It's counterproductive to do it while busy with something else. It overworks you all right, and it demands much more rigor than art.
All revolutionary new technology is initially inefficient, and requires spending a lot of time and money on finding efficient solutions. First electronic computers were terribly unwieldy, expensive, and unreliable. This equally applies to first printing presses, first steam engines, first aircraft, first jet engines, first lasers, first LLMs (arguably still applies). It's really hard to advance technology without spending large amounts of resources without any profit, or a guarantee thereof, for years and years. This requires a large cache of such resources, prepared to be burnt on R&D.
It's investment into far future vs predictable present, VC vs day trading.
I wonder why "best show ever made" always has contenders made in the last 30 years. You Bet Your Life with Groucho Marx was such a fascinating show, and had some of the most intriguing, raw conversations with ordinary people, ever. Not to mention Groucho's natural instinct for wordplay that just never failed him.
Look at some of the most famous success stories in comedy, art, music, theatre, film, etc.
A good number of them did their best work when they were poor.
"Community" is a great example. Best show ever made, hands down. Yet they were all relatively broke and overworked during the whole thing.
It's because they believed in the vision.
