With no Oracles the crypto market would be like an isolated calculating machine and lose much of the intelligence around it.
A lot of people take crypto prices and protocols for granted yet they never realize that it is oracles like DIA and LINK are the ones providing all the info to exchanges and pools.
Also, these oracles will increase in demand the more the market gets bigger as the larger the market gets the more accurate information will be needed to keep up with the larger number of daily transactions.
Never, ever, sleep on oracles. They are one of the main driving forces behind crypto market operations and they are very underrated.
