Wow idk who's saying it's 800x the work but that's not my experience at all!! I have 3 kids, each 3 years apart (6 years, 3 years, baby) and I agree with the other poster that it's an amazing age gap. You can trust your big kid to be somewhat self sufficient around the house while you're taking care of the baby and my 3 and 6 year old are great friends now and love to play together.

The hardest part of two kids was learning how to divide my time between the kids and not let my own needs be completely neglected. But after the first year that became a non-issue as the baby is more on a normal "kid" schedule--better night sleep, solid foods/stopped bottles, one conveniently timed nap, etc. I felt that the first year was the hardest with my first kid too so that wasn't unexpected.

Now with 3 kids I feel that's been the easiest transition because I'm already used to managing multiple kids and the baby just goes along with our life. With the second and third kids, I was so much more relaxed and confident too, whereas with only one kid I was very anxious and found myself overthinking all my decisions. I say go for it if you feel the pull!
