Sure are. The mailroom boy at Space-X has more computing power in his cell phone than NASA had in total when man landed on the Moon.
Space-X has sent a capsule, designed for 7 persons, into orbit, and recovered it successfully. At a much, much lower cost than NASA managed.
The Saturn V was capable of launching about 262K lbs into LEO, while the Falcon Heavy is rated at 120K lbs into LEO.
Of course, everything is lighter and more functional today than it was in the '60s.

Yes, the Falconheavy will be a significant step towards getting back to the 1970s.
Thank God for generation X. 40 years of boomers pissing away the space program.
