I'd like to share something that I've been thinking about a few times over the last few weeks when observing the occasional argument about Sketch and it's relationship to Adobe's products. Please take this as opinion and observation, not preaching. I'd love to hear reactions.
I think a few people need reminding that Sketch is not a replacement for software like Photoshop, Illustrator, InDesign etc. Sketch solves a more specific problem than all of those.
Sketch a vector design tool created by and for a group of people who want to design interactive screen-based elements, not flat, print-based elements. Yes, you can use it for print design, but the print designer is not the target market (at least, for now).
Photoshop and Illustrator started as tools for a group of people who wanted to design primarily for print. I ask you - is Photoshop even supposed to be a web design tool? Just read the name: Photoshop. It just happens to be suitable for designing websites, but I don't think that's what it was designed for.
It's no wonder that Bohemian Coding can waltz onto the scene, throw together an app in a couple of years and massively improve productivity of many screen designers. They had the benefit of years of watching people turn Adobe's products into web design tools when that wasn't their original aim. They could see what works and what doesn't work, and apply it to their own product.
Adobe took their products into web design territory and yes, people have done very well and will continue to do well with them, but do not forget that there are a lot of designers out there who are not interested in web and UI design who still use Photoshop and Illustrator, and will never use Sketch. These products are mature, have many features and include powerful tooling suitable for a wide range of tasks. They likely aren't going anywhere soon.
I guess my point is this: it's great if you're enjoying using Sketch - I am too - but Adobe is not going down, and I don't think they deserve to, either. Bohemian and Adobe can exist side-by-side and complement each other. Perhaps if Illustrator and InDesign are standard tools for print designers and Photoshop is a standard tool for Photographers, Sketch can be a standard tool for screen designers and we can all dip in and out of each others' toolkits when the need arises.
