@sarahk lol! Yes, digital marketing is growing and will continue to do so. Did you have a specific question about it?
Is this your only question? There's tons of resources online pointing to a resounding answer. Digital marketing has evened out the playing field for small business or startups and larger companies or enterprises. With this in mind competition is pretty steep, and you have to look for the best digital marketing strategies that you can tailor for your business. You can jump on the bandwagon all you like, but it's not going to be an easy ride.
