Does anyone encourage them?
Pop music in its various flavours is very much at the mercy of narrow-minded commerce interested in only the ephemeral and latest. That was always so but it seems becoming ever more crushing professionally and artistically.
If published by a streaming service, even if the company pays all the royalties due (questionable) it is likely to delete the recording after some time that probably has no artistic merit or purpose. I think the same applies to films.
There is little encouragement to be creative - many of the Big Names now are so as celebrities rather than creatives. Their works are all derivative, to match the fashion probably driven by commercial publishers like Amazon and commercial-radio. I don't know what proportion of them can even strum a few chords, write a single rhyming couplet and attach it to a few crochets, or sing in pitch.
In the UK at least, there are far fewer music shops - i.e. shops that sell instruments and equipment, sheet-music, manuscript books. The record shops have largely gone, as well, shrinking via those depressing baskets of "Best of..." anthologies on tapes then CDs sold in supermarkets and motorway-services. Who decides what is the "best", of whom, how?
Many schools are reported to have pushed the arts off the curriculum, or at least side-lined them, under government-inspired ("inspired"?) initiatives to spend dwindling funds on the so-called "STEM" * subjects as priority. Fortunately this is not universal - some schools do still have excellent arts as well as the technical departments.
We have also lost many live-music venues, especially pubs, for the amateur and semi-professional bands. Although most of those play covers, some as "tribute bands", they are bands: whatever their material they do play their own instruments. At least this provides a sort of apprenticeship for the few who manage to go beyond and start making a name for themselves with their own works.
The future is not all bleak. That is primarily about pop and rock but while they stagnate on the whims of huge commercial imperatives, the "classical" field covers a vast range of styles not only Classical, and appears very healthy. A lot of music, both existing and newly-composed, is being released by independent publishers in various ways including CDs and even vinyl. A lot of music is being composed now, many young musicians are entering this field.
