I don't know who needs to hear this, but if you think accessibility is complex, it's because you, or someone you hired, wants it to be.
Yes, we have specific guidelines for accordions, buttons, carousels, and whatnot. And we have to take into account people who are blind, hard of hearing, have fine motor disabilities, are colour blind, are in a wheelchair or can't use their hands.
Yes, disability is complex, and people's experiences of being disabled are diverse. Different people will have different access needs and sometimes these needs conflict with each other. This makes accessibility and catering to all these diverse needs incredibly complex.
But let's be real - life itself is complex. And that's because we as people are complex, unique individuals, with unique experiences and abilities. A plane, train, bus or car is complex, but we can't go through life without being on one. Your computer, your smart phone and your smart watch are complex machineries, but you use one every day.
Complexity isn't a roadblock, it's challenge we need to solve. It's something worth solving. And anything worth doing is worth doing right.
So, if someone tries to sell you the narrative that accessibility is too complex, just remind them that this is an opportunity to do things right.
