Yes, they're first to market with a 64 bit smartphone...that's of no use. This effectively moves progress horizontally instead of propelling them forward until people can make productive use of the features. Second, the criticisms are levelled against Apple because no one can conceptualize its utility. It's very hard to conceive of a phone that needs what a 64 bit processor makes possible that a 32 bit one doesn't for these types of devices. Desktops/notebooks - it makes sense for reasons related to memory usage and mathematical reasons.
*sigh* Apple IS in front and ready for the future now. Some apps can benefit now from the 64-bit move. Others will need recompiling (I read of one developer who did it in 2 hours). Saying Apple is premature in bringing 64-bit processing to the iPhone when the apps aren't ready to take advantage of it is like saying Apple was premature in bringing Retina Display because no apps had the graphics for it. Ditto for the gyroscope and any number of other new features. Or the move from PPC to Intel. No one can be ready for non-existant hardware! Here's a good quote from an article with some experts weighing in:

Quote from article: Apple's iPhone 5s, the A7 Chip, and That 64-Bit Question - John Paczkowski - Mobile - AllThingsD

But chip experts say that there are some gains to be had even from a 64-bit chip without 4GB of addressable memory.
For one thing, 64-bit integer math will allow the A7 to execute operations much faster than the 32-bit A6. “The fact that the A7 has twice as many processor registers means that more operations can occur without the processor using main memory, which is slower to access,” Carl Howe, VP of research and data sciences at the Yankee Group told AllThingsD. “This means that for some codes, the A7 will be twice as fast (or faster depending on how many memory accesses the original code had) to run code because the processor doesn’t have to use main memory as much.”
But for most, the gains found here will be marginal, said Moor Insights analyst Paul Teich. “Double the register file adds a few percent to performance,” he said. “It’s a deep compiler and runtime VM issue. … So marginal improvements for most apps, at best. Depending on how code is written it can run a little longer without hitting main memory, but it really depends on whether you are writing a computationally intensive app or not.”
Another benefit: ARMv8, the architecture on which the A7 is likely based, has a very efficient instruction set that’s great for resource-intensive applications. As Kevin Krewell, senior analyst at the Linley Group and a senior editor of Microprocessor Report, told AllThingsD, “The ARMv8 instruction set is a clean-slate approach with many improvements. Even without 4GB of RAM, the A7 should make it easier to build larger applications like PC-class games and programs. Apps can now become real desktop-class programs and games.”
The caveat here is that Apple must maintain backward compatibility with legacy 32-bit apps until the 64-bit ecosystem really kicks in. Said Krewell, “The vast majority of programs will still use the 32-bit mode, so the benefits may be slow to come."
I'm reminded of the feature of Ubuntu's phone OS where you can dock your phone and use it as a desktop computer. Apple's move here to 64-bit may be laying the groundwork for just such an option. Some time back, they had patents filed (and awarded?) for docking a smaller device to a monitor and using it as a desktop computer. So at the least, we know they have been considering it.

Please verify and include the exact model/year of your Mac and OS X version number (available from "About This Mac", then "More Info" on the Apple menu).
