As long as there are VCs that are willing to fund, companies that are willing to acquire (demand), there will be developers looking to 'mine' (supply).
If enough people who made 'loss' in this ecosystem were to exit this ecosystem then 'mining' will be obsoleted. However, there are always people/companies looking for a quick-buck/fix to inflate their bank balance or complement their product line, therefore perpetuating 'mining'.
